The present invention generally relates to a composition and, more specifically, to a composition comprising a branched organosilicon compound and an acrylate-functional compound for preparing a copolymer, and to the copolymer formed therewith and related end use applications thereof.
Silicones are polymeric materials used in numerous commercial applications, primarily due to significant advantages they possess over their carbon-based analogues. More precisely called polymerized siloxanes or polysiloxanes, silicones have an inorganic silicon-oxygen backbone chain ( . . . —Si—O—Si—O—Si—O— . . . ) with organic side groups attached to the silicon atoms.
Organic side groups may be used to link two or more of these backbones together. By varying the —Si—O— chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxane is linear polydimethylsiloxane (PDMS), a silicone oil. The second largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes.
Another group of silicone materials are silicone dendrimers. Dendrimers are polymers that have a highly branched structure which extends radially from a single core. A dendrimer is a repetitively branched molecule, typically symmetric (or near symmetric) around the core, and often adopts a spherical or ellipsoidal three-dimensional morphology. Dendritic polymers can also be described as tree-like macromolecules consisting of unique branch-upon-branch-upon-branch structural organizations or generations.
Dendritic silicones or macromolecules have molecular shapes, sizes, and functionality that provide for many potential end applications. Thus, there remains an opportunity to provide improved branched compounds based on silicon, as well as improved methods of forming such compounds. There also remains an opportunity to provide improved copolymers and improved compositions based on or having such compounds.
A composition is provided. The composition comprises: a branched organosilicon compound; an acrylate-functional compound other than the branched organosilicon compound; and optionally a carrier vehicle.
The branched organosilicon compound has the following general formula (I):
where X comprises a acryloxy-functional moiety, and each R1 is selected from —OSi(R4)3 and R, with the proviso that at least one R1 is —OSi(R4)3; where each R is a substituted or unsubstituted hydrocarbyl group; where each R4 is selected from R, —OSi(R5)3, and —[OSiR2]mOSiR3; where each R5 is selected from R, —OSi(R6)3, and —[OSiR2]mOSiR3; where each R6 is selected from R and —[OSiR2]mOSiR3; with the proviso that at least one of R4, R5 and R6 is —[OSiR2]mOSiR3; and where 0≤m≤100.
A method of preparing a copolymer is further provided. The method comprises reacting the branched organosilicon compound and the acrylate-functional compound in the presence of the carrier vehicle. A copolymer formed in accordance with the method is further provided. In addition, a film formed with or by the copolymer is provided. Further still, a composition comprising the copolymer and a carrier vehicle is provided.
A composition comprises a branched organosilicon compound. The branched organosilicon compound has the following general formula (I):
where X comprises an acryloxy-functional moiety, and each R1 is selected from —OSi(R4)3 and R, with the proviso that at least one R1 is —OSi(R4)3; where each R is a substituted or unsubstituted hydrocarbyl group; where each R4 is selected from R, —OSi(R5)3, and —[OSiR2]mOSiR3; where each R5 is selected from R, —OSi(R6)3, and —[OSiR2]mOSiR3; where each R6 is selected from R and —[OSiR2]mOSiR3; with the proviso that at least one of R4, R5 and R6 is —[OSiR2]mOSiR3; and where 0≤m≤100.
Each R is independently selected and may be linear, branched, cyclic, or combinations thereof. Cyclic hydrocarbyl groups encompass aryl groups as well as saturated or non-conjugated cyclic groups. Cyclic hydrocarbyl groups may be monocyclic or polycyclic. Linear and branched hydrocarbyl groups may independently be saturated or unsaturated. One example of a combination of a linear and cyclic hydrocarbyl group is an aralkyl group. By “substituted,” it is meant that one or more hydrogen atoms may be replaced with atoms other than hydrogen (e.g. a halogen atom, such as chlorine, fluorine, bromine, etc.), or a carbon atom within the chain of R may be replaced with an atom other than carbon, i.e., R may include one or more heteroatoms within the chain, such as oxygen, sulfur, nitrogen, etc. Suitable alkyl groups are exemplified by, but not limited to, methyl, ethyl, propyl (e.g., iso-propyl and/or n-propyl), butyl (e.g., isobutyl, n-butyl, tert-butyl, and/or sec-butyl), pentyl (e.g., isopentyl, neopentyl, and/or tert-pentyl), hexyl, as well as branched saturated hydrocarbon groups of 6 carbon atoms. Suitable aryl groups are exemplified by, but not limited to, phenyl, tolyl, xylyl, naphthyl, benzyl, and dimethyl phenyl. Suitable alkenyl groups include vinyl, allyl, propenyl, isopropenyl, butenyl, isobutenyl, pentenyl, heptenyl, hexenyl, and cyclohexenyl groups. Suitable monovalent halogenated hydrocarbon groups include, but are not limited to, a halogenated alkyl group of 1 to 6 carbon atoms, or a halogenated aryl group of 6 to 10 carbon atoms. Suitable halogenated alkyl groups are exemplified by, but not limited to, the alkyl groups described above where one or more hydrogen atoms is replaced with a halogen atom, such as F or Cl. For example, fluoromethyl, 2-fluoropropyl, 3,3,3-trifluoropropyl, 4,4,4-trifluorobutyl, 4,4,4,3,3-pentafluorobutyl, 5,5,5,4,4,3,3-heptafluoropentyl, 6,6,6,5,5,4,4,3,3-nonafluorohexyl, and 8,8,8,7,7-pentafluorooctyl, 2,2-difluorocyclopropyl, 2,3-difluorocyclobutyl, 3,4-difluorocyclohexyl, and 3,4-difluoro-5-methylcycloheptyl, chloromethyl, chloropropyl, 2-dichlorocyclopropyl, and 2,3-dichlorocyclopentyl are examples of suitable halogenated alkyl groups. Suitable halogenated aryl groups are exemplified by, but not limited to, the aryl groups described above where one or more hydrogen atoms is replaced with a halogen atom, such as F or Cl. For example, chlorobenzyl and fluorobenzyl are suitable halogenated aryl groups.
In specific embodiments, each R is independently an alkyl group having from 1 to 10, alternatively from 1 to 8, alternatively from 1 to 6, alternatively from 1 to 4, alternatively from 1 to 3, alternatively from 1 to 2, alternatively 1, carbon atom(s).
Each R1 is selected from R and —OSi(R4)3, with the proviso that at least one R1 is —OSi(R4)3. In certain embodiments, at least two of R1 are —OSi(R4)3. In specific embodiments, all three of R1 are —OSi(R4)3. When a greater number of R1 are —OSi(R4)3, the organosilicon compound has a greater level of branching. For example, when each R1 is —OSi(R4)3 and the Si—X bond is a silicon-carbon bond, the silicon atom to which each R1 is bonded is a T siloxy unit. Alternatively, when two of R1 are —OSi(R4)3 and the Si—X bond is a silicon-carbon bond, the silicon atom to which each R1 is bonded is a D siloxy unit.
Each R4 is selected from R, —OSi(R5)3, and —[OSiR2]mOSiR3, where 0≤m≤100. Depending on a selection of R4 and R5, further branching can be present in the branched organosilicon compound. For example, when each R4 is R, then each —OSi(R4)3 moiety is a terminal M siloxy unit. Said differently, when each R1 is —OSi(R4)3, and when each R4 is R, then each R1 can be written as OSiR3, and each R1 is an M siloxy unit. In such embodiments, the branched organosilicon compound includes a T siloxy unit (to which X is bonded) capped by three M siloxy units. When R4 is —[OSiR2]mOSiR3, R4 includes optional D siloxy units (i.e., those siloxy units in the moiety indicated by subscript m), and an M siloxy unit (represented by OSiR3). Thus, for example, when each R1 is —OSi(R4)3, and when each R4 is —[OSiR2]mOSiR3, then each R1 includes a Q siloxy unit. In such embodiments, each R1 is of formula —OSi([OSiR2]mOSiR3)3. When each m is 0, each R1 is a Q siloxy unit endcapped with three M siloxy units. When m is greater than 0, each R1 includes a linear moiety with a degree of polymerization being attributable to m. This linear moiety, if present, is generally a diorganosiloxane moiety.
Subscript m is from (and including) 0 to 100, alternatively from 0 to 80, alternatively from 0 to 60, alternatively from 0 to 40, alternatively from 0 to 20, alternatively from 0 to 19, alternatively from 0 to 18, alternatively from 0 to 17, alternatively from 0 to 16, alternatively from 0 to 15, alternatively from 0 to 14, alternatively from 0 to 13, alternatively from 0 to 12, alternatively from 0 to 11, alternatively from 0 to 10, alternatively from 0 to 9, alternatively from 0 to 8, alternatively from 0 to 7, alternatively from 0 to 6, alternatively from 0 to 5, alternatively from 0 to 4, alternatively from 0 to 3, alternatively from 0 to 2, alternatively from 0 to 1, alternatively is 0. Typically, each subscript m is 0 such that the branched moiety of the branched organosilicon compound is free from D siloxy units.
As set forth above, each R4 can also be —OSi(R5)3. In such embodiments, depending a selection of R5, further branching can be present in the branched organosilicon compound. Each R5 is selected from R, —OSi(R6)3, and —[OSiR2]mOSiR3, where m is defined above; where each R6 is selected from R and —[OSiR2]mOSiR3, where m is defined above. At least one of R4, R5 and R6 is —[OSiR2]mOSiR3, where m is defined above. When R1 is of formula —OSi(R4)3, and when R4 is of formula —OSi(R5)3, further siloxane bonds and branching is present in the branched organosilicon compound. This is further the case when R5 is —OSi(R6)3
In particular, each subsequent R moiety in the branched organosilicon compound can impart a further generation of branching. For example, R1 can be of formula —OSi(R4)3, R4 can be of formula —OSi(R5)3, and R5 can be —OSi(R6)3. Thus, depending on a selection of each substituent, further branching attributable to T and/or Q siloxy units may be present in the branched organosilicon compound.
Importantly, each of R, R1, R4, R5, and R6 are independently selected. As such, the descriptions above relating to each of these substituents is not meant to mean or imply that each substituent is the same. Any description above relating to R1 may relate to only one R1 or any number of R1 in the branched organosilicon compound, and so on.
In addition, different selections of R, R1, R4, R5, and R6 can result in the same structures. For example, if R1 is —OSi(R4)3, and if each R4 is —OSi(R5)3, and if each R5 is R, then R1 can be written as —OSi(OSiR3)3. Similarly, if R1 is —OSi(R4)3, and if each R4 is —[OSiR2]mOSiR3, where m is 0, then R1 can be written as —OSi(OSiR3)3. This results in the same structure for R1 based on different selections for R4. To that end, at least one of R4, R5 and R6 is —[OSiR2]mOSiR3. However, when m is 0, this proviso can be inherently met through alternative selections. For example, as noted above, if each R4 is —OSi(R5)3, and if each R5 is R, then R1 can be written as —OSi(OSiR3)3, which is the same as if R1 is —OSi(R4)3, and if each R4 is —[OSiR2]mOSiR3, where m is 0. It shall be considered that the proviso is met even if alternative selections can result in the same structures as required in the proviso.
In certain embodiments, each R1 is —OSi(R4)3. In specific embodiments in which each R1 is —OSi(R4)3, at least one R4 is —[OSiR2]mOSiR3, where m is 0. Because m is 0, the at least one R4 is —OSiR3. This is the same structure as if at least one R4 is —OSi(R5)3, and if each R5 is R. Both selections result in at least one R4 being —OSiR3. Thus, if at least one R4 is —OSi(R5)3, and if each R5 is R, it shall also be considered that at least one of R4 is —[OSiR2]mOSiR3, where m is 0.
The same is true for further generations of branching in the branched organosilicon compound. For example, just as different selections associated with R4 and R5 can result in the same structure above, different selections for R5 and R6 can similarly result in the same structure.
In certain embodiments, each R1 is —OSi(R4)3. In specific embodiments in which each R1 is —OSi(R4)3, one R4 is R in each —OSi(R4)3 such that each R1 is —OSiR(R4)2. In further specific embodiments, two R4 in —OSiR(R4)2 are each —OSi(R5)3 moieties such that the branched organosilicon compound has the following structure:
where R is independently selected and defined above, and each R5 is independently selected and defined above, and X is defined above. In certain embodiments, each R5 is R, and each R is methyl.
As noted above, the same structure of the branched organosilicon compound can result from different selections. For example, the same branched organosilicon compound as exemplified above results with the following selections: each R1 is —OSi(R4)3, where one R4 is R and two of R4 are —[OSiR2]mOSiR3, where m is 0. Thus, in the structure exemplified above, the proviso that at least one of R4, R5 and R6 be —[OSiR2]mOSiR3 is met regardless of the selections of R4 and R5 utilized to arrive at the resulting structure.
In other embodiments, one R1 is R, and two of R1 are —OSi(R4)3. In specific embodiments in which two of R1 is —OSi(R4)3, one R4 is R in each —OSi(R4)3 such that two of R1 are —OSiR(R4)2. In further specific embodiments, each R4 in —OSiR(R4)2 is —OSi(R5)3 such that the branched organosilicon compound has the following structure:
where R is independently selected and defined above, and each R5 is independently selected and defined above, and X is defined above. In certain embodiments, each R5 is R, and each R is methyl.
As noted above, the same structure of the branched organosilicon compound can result from different selections. For example, the same branched organosilicon compound as exemplified above results with the following selections: one R1 is R; two of R1 are —OSi(R4)3, where one R4 is R and two of R4 are —[OSiR2]mOSiR3, where m is 0, in each —OSi(R4)3. Thus, in the structure exemplified above, the proviso that at least one of R4, R5 and R6 be —[OSiR2]mOSiR3 is met regardless of the selections of R4 and R5 utilized to arrive at the resulting structure.
In yet other embodiments, two of R1 are R, and one R1 is —OSi(R4)3. In specific embodiments in which one of R1 is —OSi(R4)3, and one R4 is R in —OSi(R4)3 such that this specific R1 is —OSiR(R4)2. In further specific embodiments, each R4 in —OSiR(R4)2 is —OSi(R5)3 such that the branched organosilicon compound has the following structure:
where R is independently selected and defined above, and each R5 is independently selected and defined above, and X is defined above. In certain embodiments, each R5 is R, and each R is methyl.
As noted above, the same structure of the branched organosilicon compound can result from different selections. For example, the same branched organosilicon compound as exemplified above results with the following selections: two of R1 are R; one of R1 is —OSi(R4)3, where one R4 is R and two of R4 are —[OSiR2]mOSiR3, where m is 0, in —OSi(R4)3. Thus, in the structure exemplified above, the proviso that at least one of R4, R5 and R6 be —[OSiR2]mOSiR3 is met regardless of the selections of R4 and R5 utilized to arrive at the resulting structure.
In the exemplary structures set forth above, each R5 is R, and each R is methyl. However, further generational branching can be introduced into the branched organosilicon compound when R5 is other than R, i.e., when R5 is selected from OSi(R6)3, and —[OSiR2]mOSiR3, where m is defined above; where each R6 is selected from R and —[OSiR2]mOSiR3, where m is defined above.
As set forth above, X comprises an acryloxy-functional moiety. In certain embodiments, X has formula -D-R2, where D is a divalent linking group and R2 is an acryloxy group.
Each D is an independently selected divalent hydrocarbon group having from 2 to 18 carbon atoms, alternatively from 2 to 16 carbon atoms, alternatively from 2 to 14 carbon atoms, alternatively from 2 to 12 carbon atoms, alternatively from 2 to 10 carbon atoms, alternatively from 2 to 8 carbon atoms, alternatively from 2 to 6 carbon atoms, alternatively from 2 to 4 carbon atoms, alternatively 3 carbon atoms, alternatively 2 carbon atoms. Each D may independently be linear or branched. For example, when D has two carbon atoms, D has formula C2H4, and may be linear (CH2CH2) or branched (CHCH3). In certain embodiments, D is linear. In specific embodiments, each D is C3H6. D may optionally include one or more heteroatoms. For example, in one embodiment, D comprises an ether moiety.
R2 is an acryloxy group of the formula:
where R8 is independently selected from hydrocarbyl groups and H. In some such embodiments, R8 is H or —CH3.
Acrylate Compound
The composition further comprises an acrylate-functional compound. The acrylate-functional compound is not limited and may any acrylate-functional compound, as described in further detail below. The term “acrylate-functional compound,” as used herein, means a compound or molecule including at least one, alternatively at least two, acrylate functional groups (e.g. alkyl acrylate groups such as methyl, ethyl, or butyl acrylate groups, substituted acrylate groups such as a 2-ethylhexyl or hydroxyl ethyl groups, and others such as a methylolpropane acrylate groups, etc.). As will be understood in view of the description herein, the acrylate-functional compound may be monomeric, oligomeric, polymeric, aliphatic, aromatic, araliphatic, etc. In addition, the copolymer may comprise a number of different acrylate-functional groups, which are independently selected.
Acrylate compounds and methods of preparing acrylate-functional compounds are known in the art. For example, polyacrylates may be prepared via a conventional radical polymerization of acrylic monomers. Such conventional methods are generally carried out by combining radically-polymerizable monomers (e.g. acrylate monomers, comonomers, etc.) in the presence of a radical initiator/generator, such as a thermo-, chemo, and/or photopolymerization initiator. For example, peroxides and aromatic initiators (e.g. phenols, benzoins, heterocylcles such as imidazoles, etc.) are commonly utilized. These conventional methods may be used to prepare acrylate homopolymers and copolymers, including ternary, quaternary, and higher-order copolymers. Additionally, di- and/or multifunctional acrylic monomers may also be utilized, e.g. to prepare multifunctional polyacrylates (and polyacrylate compounds), as will be understood in view of the description of suitable acrylic monomers herein.
In general, methods of preparing acrylate-functional compounds utilize at least one acrylic monomer having an acryloyloxy or alkylacryloyloxy group (i.e., acrylates, alkylacrylates, acrylic acids, alkylacrylic acids, and the like, as well as derivatives and/or combinations thereof). Such acrylic monomers may be monofunctional or polyfunctional acrylic monomers.
Examples of specific monofunctional acrylic monomers suitable for preparing polyacrylates (and polyacrylate moieties) include (alkyl)acrylic compounds, such as methyl acrylate, phenoxyethyl (meth)acrylate, phenoxy-2-methylethyl (meth)acrylate, phenoxyethoxyethyl (meth)acrylate, 3-phenoxy-2-hydroxypropyl (meth)acrylate, 2-phenylphenoxyethyl (meth)acrylate, 4-phenylphenoxyethyl (meth)acrylate, 3-(2-phenylphenyl)-2-hydroxypropyl (meth)acrylate, polyoxyethylene-modified p-cumylphenol (meth)acrylate, 2-bromophenoxyethyl (meth)acrylate, 2,4-dibromophenoxyethyl (meth)acrylate, 2,4,6-tribromophenoxyethyl (meth)acrylate, polyoxyethylene-modified phenoxy (meth)acrylate, polyoxypropylene-modified phenoxy (meth)acrylate, polyoxyethylene nonylphenyl ether (meth)acrylate, isobornyl (meth)acrylate, 1-adamantyl (meth)acrylate, 2-methyl-2-adamantyl (meth)acrylate, 2-ethyl-2-adamantyl (meth)acrylate, bornyl (meth)acrylate, tricyclodecanyl (meth)acrylate, dicyclopentanyl (meth)acrylate, dicyclopentenyl (meth)acrylate, cyclohexyl (meth)acrylate, 4-butylcyclohexyl (meth)acrylate, acryloylmorpholine, 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate, 2-hydroxybutyl (meth)acrylate, methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, isopropyl (meth)acrylate, butyl (meth)acrylate, amyl (meth)acrylate, isobutyl (meth)acrylate, t-butyl (meth)acrylate, pentyl (meth)acrylate, isoamyl (meth)acrylate, hexyl (meth)acrylate, heptyl (meth)acrylate, octyl (meth)acrylate, isooctyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, nonyl (meth)acrylate, decyl (meth)acrylate, isodecyl (meth)acrylate, undecyl (meth)acrylate, dodecyl (meth)acrylate, lauryl (meth)acrylate, stearyl (meth)acrylate, isostearyl (meth)acrylate, benzyl (meth)acrylate, 1-naphthylmethyl (meth)acrylate, 2-naphthylmethyl (meth)acrylate, tetrahydrofurfuryl (meth)acrylate, butoxyethyl (meth)acrylate, ethoxydiethylene glycol (meth)acrylate, poly(ethylene glycol) mono(meth)acrylate, poly(propylene glycol) mono(meth)acrylate, methoxyethylene glycol (meth)acrylate, ethoxyethyl (meth)acrylate, methoxypoly(ethylene glycol) (meth)acrylate, methoxypoly(propylene glycol) (meth)acrylate, diacetone (meth)acrylamide, isobutoxymethyl (meth)acrylamide, N,N-dimethyl (meth)acrylamide, t-octyl (meth)acrylamide, dimethylaminoethyl (meth)acrylate, diethylaminoethyl (meth)acrylate, 7-amino-3,7-dimethyloctyl (meth)acrylate, N,N-diethyl (meth)acrylamide, N,N-dimethylaminopropyl (meth)acrylamide, and the like, as well as derivatives thereof.
Examples of specific polyfunctional acrylic monomers suitable for preparing polyacrylates (and polyacrylate moieties) include (alkyl)acrylic compounds having two or more acryloyl or methacryloyl groups, such as trimethylolpropane di(meth)acrylate, trimethylolpropane tri(meth)acrylate, polyoxyethylene-modified trimethylolpropane tri(meth)acrylate, polyoxypropylene-modified trimethylolpropane tri(meth)acrylate, polyoxyethylene/polyoxypropylene-modified trimethylolpropane tri(meth)acrylate, dimethyloltricyclodecane di(meth)acrylate, pentaerythritol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, ethylene glycol di(meth)acrylate, tetraethylene glycol di(meth)acrylate, phenylethylene glycol di(meth)acrylate, poly(ethylene glycol) di(meth)acrylate, poly(propylene glycol) di(meth)acrylate, 1,4-butanediol di(meth)acrylate, 1,6-hexanediol di(meth)acrylate, neopentyl glycol di(meth)acrylate, 1,9-nonanediol di(meth)acrylate, 1,10-decanediol di(meth)acrylate, 1,3-adamantanedimethanol di(meth)acrylate, o-xylylene di(meth)acrylate, m-xylylene di(meth)acrylate, p-xylylene di(meth)acrylate, tris(2-hydroxyethyl)isocyanurate tri(meth)acrylate, tris(acryloyloxy) isocyanurate, bis(hydroxymethyl)tricyclodecane di(meth)acrylate, dipentaerythritol penta(meth)acrylate, dipentaerythritol hexa(meth)acrylate, polyoxyethylene-modified 2,2-bis(4-((meth)acryloxy)phenyl)propane, polyoxypropylene-modified 2,2-bis(4-((meth)acryloxy)phenyl)propane, and polyoxyethylene/polyoxypropylene-modified 2,2-bis(4-((meth)acryloxy)phenyl)propane.
It is to be appreciated that the (alkyl)acrylic compounds above are described in terms of (meth)acrylate species only for brevity, and that one of skill in the art will readily understand that other alkyl and/or hydrido versions of such compounds may equally be utilized. For example, one of skill in the art will understand that the monomer “2-ethylhexyl (meth)acrylate” listed above exemplifies both 2-ethylhexyl (meth)acrylate as well as 2-ethylhexyl acrylate. Likewise, while the acrylic monomers are described generally as propenoates (i.e., α,β-unsaturated esters) in the examples above, it is to be appreciated that the that the term “acrylate” used in these descriptions may equally refer to an acid, salt, and/or conjugate base of the esters exemplified. For example, one of skill in the art will understand that the monomer “methyl acrylate” listed above exemplifies the methyl ester of acrylic acid, as well as acrylic acid, acrylate salts (e.g. sodium acrylate), etc. Furthermore, multifunctional derivatives/variations of the acrylic monomers described above may also be utilized. For example, the monomers “ethyl (meth)acrylate” listed above exemplifies functionalized-derivatives, such as substituted ethyl (meth)acrylates and ethyl acrylates (e.g. hydroxyethyl (meth) acrylate and hydroxyethyl acrylate, respectively).
Comonomers (i.e., monomers reactive with the acrylic monomers above) may also be utilized to prepare or otherwise present with the acrylate-functional compounds. Such monomers are not limited, and generally include compounds having a radically polymerizable group, such as an alkenyl, acryloyl, and alkylacryloyl groups. In general, comonomers are selected by one of skill the in art, e.g. to alter a property of the acrylate-functional compound and/or the copolymer formed therewith. For example, it is known in the art that styrene may be copolymerized with an acrylic monomer to prepare polyacrylates (and polyacrylate moieties) having increased hardness as compared to those absent such styrene comonomers. Likewise, comonomers such as acrylonitrile may be utilized to increase interchain polar interactions, and thus increase tensile strength and ultimate elongation of polyacrylates (and polyacrylate moieties), while also decreasing low temperature flexibility of such polyacrylates (and polyacrylate moieties). Moreover, one of skill in the art will readily selected the proportion(s) of monomers utilized, the order of addition, the length of reaction, and other factors to independently tune various properties (e.g. flexibility, solubility, hardness, polarity, etc.) of the polyacrylate moiety, the copolymer comprising the polyacrylate moiety, and/or compositions and/or products prepared therefrom. Specific examples of suitable comonomers include styrene, acrylonitrile, vinylidene chloride, vinyl chloride, ethylene, propylene, butylene, chloroprene, isoprene, tetrafluoroethylene, and the like, as well as derivatives thereof.
It is to be appreciated that combinations of acrylic monomers may also be utilized as or to prepare the acrylate-functional compound, such that the acrylate-functional compound may be homopolymeric or copolymeric with respect to any repeating segments therein. For example, the methods described above may be utilized to prepare multifunctional polyacrylates, e.g. by utilizing a monofunctional acrylic monomer and a polyfunctional acrylic monomer. These different functional monomers are typically selected by one of skill in the art, e.g. based on the reactivity and interpolymeric and/or intrapolymeric interactivity, to alter the mechanical strength of the polyacrylate prepared therewith. For example, cured products comprising the copolymer utilizing a polyacrylate moiety comprising a combination of monofunctional acrylic monomers and polyfunctional acrylic monomers can be prepared with increased mechanical strength as compared to those utilizing a homopolymeric polyacrylate moieties. Likewise, cured products comprising the copolymer utilizing a homopolymeric polyacrylate moiety may be prepared having increased flexibility as compared to those utilizing a polyfunctional polyacrylate moieties.
In specific embodiments, the acrylate-functional compound comprises or is prepared from methyl (meth)acrylate, methyl acrylate, butyl (meth)acrylate, butyl acrylate, 2-ethylhexyl (meth)acrylate, 2-ethylhexyl acrylate, hydroxyethyl (meth)acrylate, hydroxyethyl acrylate, methacrylic acid, acrylic acid, and/or styrene monomers.
It will also be appreciated that the acrylate-functional compound prepared as described above may be mono- or multifunctional with respect to the non-acrylic functional groups present therein. For example, such methods may be utilized to prepare polyacrylate alcohols, diols and/or polyols, including via the methods described above (e.g. by utilizing a hydroxyl-functional monomer) and modifications thereof (e.g. by utilizing a post-polymerization functionalization technique, such as endcapping and/or grafting a functional group-containing compound onto a polyacrylate. Such functional group-containing compounds include alkoxysilyl groups, e.g. which may be grafted onto a polyacrylate via hydrosilylation or other methods known in the art. For example, in certain embodiments, the polyacrylate moiety is prepared from a polyacrylate polyol. In these or other embodiments, the polyacrylate moiety is prepared from a polyacrylate compound comprising a dimethoxymethylsily group. In certain embodiments, the polyacrylate moiety is prepared from a polyacrylate compound comprising at least one radical polymerizable group, such as an acryloyl functional group.
The acrylate-functional compound typically has a number average molecular weight (Mn) of at least 100.

Method
A method of preparing a copolymer is further provided. The method comprises reacting the branched organosilicon compound and the acrylate-functional compound in the presence of the carrier vehicle.
Generally speaking, the branched organosilicon compound and the acrylate-functional compound react in the presence of the initiator (and the carrier vehicle, as well as an optional components present in the composition). Thus, the method of preparing the copolymer generally requires contacting the branched organosilicon compound and the acrylate-functional compound in the presence of the initiator and the carrier vehicle.
There is no required order of addition of the components to form the composition or prepare the copolymer. For example, in one embodiment, the carrier vehicle comprises water. The branched organosilicon compound and the acrylate-functional compound can be dispersed or emulsified in the water acting as the carrier vehicle (e.g. the branched organosilicon compound and the acrylate-functional compound can be combined with water in any order, optional under shear or agitation). The initiator may be disposed in the composition or emulsion to initiate preparation of the copolymer from polymerizing or reacting the branched organosilicon compound and the acrylate-functional compound. Alternatively, in other embodiments, the branched organosilicon compound and the acrylate-functional compound can be mixed together neat to give a neat mixture, and the initiator may be disposed in the carrier fluid to give an initiator mixture. The neat mixture and the initiator mixture can be combined, optionally under agitation, to give the composition and prepare the copolymer by polymerizing or reacting the branched organosilicon compound and the acrylate-functional compound.
In certain embodiments, the method is carried out at an elevated temperature, i.e., the method comprises reacting the branched organosilicon compound and the acrylate-functional compound in the presence of the carrier vehicle at an elevate temperature. The elevated temperature typically accelerates the reaction between the branched organosilicon compound and the acrylate-functional compound. In certain embodiments, the elevated temperature is from greater than 25° C. up to a boiling temperature of the carrier vehicle; alternatively from 30 to 150, alternatively from 40 C to 120, alternatively from 50 to 110, alternatively from 60 to 100, alternatively from 70 to 70, ° C. Oxygen may optionally be removed from the composition during the method, e.g. by bubbling nitrogen or another inert gas into the composition.
The branched organosilicon compound and the acrylate-functional compound can be reacted at various molar ratios. In addition, the molar ratio of the branched organosilicon compound and the acrylate-functional compound is a function of the selection of the acrylate-functional compound (and branched organosilicon compound). The relative amounts of the acrylate-functional compound may differ when the acrylate-functional compound is a monomer versus a polymer. In certain embodiments, the branched organosilicon compound and the acrylate-functional compound are reacted in a molar ratio of from 1.5:1 to 1:1.5, alternatively from 1.4:1 to 1:1.4, alternatively from 1.3:1 to 1:1.3, alternatively from 1.2:1 to 1:1.2, alternatively from 1.1:1 to 1:1.1, alternatively from 1.1:1 to 1:1. However, one of skill in the art will select the particular ratios utilized, e.g. in view of the particular copolymer being prepared, the particular branched organosilicon compound and/or acrylate-functional compound being utilized, a desired use of the copolymer being prepared, the type of reaction being utilized in the polymerization method, etc.
The copolymer is the reaction product of the branched organosilicon compound and the acrylate-functional compound. As will be appreciated by one of skill in the art in view of the description herein, many variations or species of the copolymer may be prepared, e.g. depending on the particular branched organosilicon compound utilized, the particular acrylate-functional compound utilized, the type of reaction performed, the ratio of components utilized, etc.
In general, the copolymer comprises a branched organosilicon moiety having the formula:
which is formed from the branched organosilicon compound utilized in the reaction with the reactive compound. As such, with regard to the branched organosilicon moiety of the copolymer, the organosilicon moiety represented by the subformula R13Si— is as defined above with respect to the branched organosilicon compound. Subformula —X1— is a moiety formed from the moiety X of the branched organosilicon compound (i.e., during the reaction of the branched organosilicon compound the acrylate-functional compound).
In some embodiments, the copolymer has the general formula:
where the organosilicon moiety represented by the subformula R13Si— is as defined above with respect to the branched organosilicon compound; —X1— is a moiety formed from the moiety X of the branched organosilicon compound (i.e., during the reaction of the branched organosilicon compound the acrylate-functional compound); and Z is a polymer moiety formed from the acrylate-functional compound.
Moiety X1 is formed from the moiety X of the branched organosilicon compound. As such, the particular nature (e.g. structure, formula, etc.) of X1 will be controlled by the selection of the particular branched organosilicon compound and acrylate-functional compound to be utilized in preparing the copolymer, the type of reaction used therewith, etc., as will be understood by those of skill in the art in view of the description herein.
In certain embodiments, the copolymer has the general formula:
where moieties R13Si—, —X1—, and Z are as defined above, and subscript x″ is ≥2. In such embodiments, the copolymer may comprise a linear structure, e.g. where subscript x″ is 2, and the polymer moiety Z is linear, such that the copolymer has the general structure R13Si—X1—Z—X1—Si—R13. Alternatively, the copolymer may comprise a branched structure, such as where X is at least trivalent and subscript x″ is ≥2, alternatively ≥3.
The copolymer is typically prepared in the presence of the carrier vehicle. Specific examples of the carrier vehicle are disclosed above. For example, the copolymer may be prepared in an aqueous carrier vehicle, or the copolymer may be prepared in an emulsion such that the carrier vehicle is other than water but the composition further comprises water.
Upon forming the copolymer, the copolymer may be dispersed in one or more types of oil agents, Examples of oil agents include animal oils, plant oils, synthetic oils, or the like that are generally used in cosmetics. As long as the oil agent is hydrophobic, the oil agent may be derived from any source, may be in the form of a solid, a semi-solid, or a liquid, and may be non-volatile, semi-volatile, or volatile. When the copolymer of the present invention is used in the form of the liquid composition, the oil agent may be a volatile liquid. Specific examples of suitable oil agents include silicone oils, hydrocarbon oils, and fatty acid ester oils. The oil agent may be the carrier vehicle or the copolymer may undergo an isolation or purification step, or a solvent exchange step, to be dispersed in the oil agent instead of the carrier vehicle.
The copolymer of the present invention has particularly excellent miscibility with the oil agent, and a copolymer composition may be obtained that is uniform over long durations. This composition may be used itself as a surface treatment agent without modification. Alternatively, this composition is extremely useful as a raw material for cosmetics. More particularly, a copolymer composition formed from 100 parts by mass of the copolymer of the present invention and from 5 to 1,000 parts by mass of the oil agent, alternatively from 50 to 500 parts by mass of the oil agent, alternatively from 100 to 400 parts by mass of the oil agent, may be used.

When the copolymer of the present invention is used as a cosmetic raw material, by combined use of the hydrocarbon oil and/or fatty acid ester oil with the silicone oil, in addition to the characteristic fresh feel of the silicone oil, it is possible to retain the moisture on the skin and impart a smooth feel or moisture-retaining feel (also referred to as “moist feel”) as if the skin or hair was wetted by the cosmetic. However, even when the copolymer of the present invention is used as a surface treatment agent, the copolymer of the present invention is advantageous in that time-wise stability of the cosmetic is not lost. Furthermore, with a cosmetic composition comprising the hydrocarbon oil and/or fatty acid ester oil and the silicone oil, these moisturizing components can be applied more stably and uniformly on the skin or hair, the moisturizing effects of the moisturizing component on the skin are improved and, compared to a cosmetic composition comprising only the oil agent other than the silicone oil (the hydrocarbon oil and/or fatty ester oil), a smoother, richer feeling to touch is imparted.

As understood in the art, surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. Surfactants can serve as cleaning, wetting, dispersing, emulsifying, foaming and anti-foaming agents in many practical applications and products, including, but not limited to, detergents, fabric softeners, emulsions, soaps, paints, adhesives, inks, anti-fogs, ski waxes, snowboard wax, deinking of recycled papers, in flotation, washing and enzymatic processes, laxatives, etc. Agrochemical formulations such as some herbicides, insecticides, biocides (sanitizers), and spermicides may also include one or more surfactants. Personal care products such as cosmetics, shampoos, shower gel, hair conditioners (after shampoo), and toothpastes often include one or more surfactants.
In various embodiments, the surfactant composition comprises the copolymer of this disclosure. In certain embodiments, the surfactant composition further comprises one or more additives understood in the art, such as water and/or other vehicles, one or more conventional surfactants, etc. One of skill in the art appreciates that surfactant compositions may also be referred to as wetting compositions, surface tension modifiers, or dispersant compositions. In some applications, there may be slight nuances as to differences in form, function, and/or end application of such compositions.
In other embodiments, the copolymer itself is a surfactant. In these embodiments, the copolymer may be referred to as a dispersant, a wetting agent, or a surface tension modifier.
In various embodiments, the composition is selected from the group consisting of film-forming compositions, including foaming and substantially non-foaming compositions, aqueous and non-aqueous compositions, and combinations thereof. Certain films are described below. The composition may be curable, partially curable, or may not cure. In embodiments where the composition is at least partially curable to curable, the composition can change form, such as going from a liquid to a more viscous liquid, a gel, a semi-solid, or a solid.
In various embodiments, the composition is useful as an antiblocking (or anti-blocking) additive (or agent). In these embodiments, the composition may also provide scratch resistance and a low coefficient of friction (COF). In certain embodiments, the copolymer itself is the antiblocking additive.
Antiblocking agents are often used in or for films, e.g. in polyolefin films, to improve the slippage among individual molecules of the antiblocking agent and are important ingredients for the post-processing conversion (cutting, folding, welding etc.) of such films. Blocking is a common problem encountered by manufacturers of films and coatings. Blocking is the adhesion of two adjacent layers of film. It is a problem most associated with polyethylene and polypropylene films (either blown or cast) and to a lesser extent in extrusion coated or laminated products. Blocking of adjacent film layers occurs due to the presence of van der Waals forces between the amorphous regions of the polymer. These forces increase with reduced distance between the two layers, thereby increasing blocking when two layers are pressed together (e.g. binding onto a take up roll or stacking of finished, converted films). Another possible reason for blocking is the presence of low molecular weight species (such as oligomers) which tend to migrate to the surface of the film.
An effective method for combating these handling problems is to add an antiblocking additive. An antiblocking additive present in the resin microscopically protrudes from the film surface. This creates asperities (“little bumps”) which help to minimize the film-to-film surface contact, increasing the distance between the two layers, thereby minimizing blocking.
The blocking between adjacent layers results in increased friction and the addition of an antiblocking agent generally contributes to a reduction in the film-to-film COF. COF is a measure of the relative difficulty with which one surface will slide over an adjoining surface.

In certain embodiments, the personal care ingredient comprises a film-forming polymer, which may be utilized as the personal care ingredient whether the composition is utilized for skin care, hair care, etc. “Film-forming polymer,” as used herein, means a polymer or oligomer which is capable of, by itself or optionally in the presence of a film-forming agent, forming a film on a substrate. The film-forming polymer may form the film upon an application of a curing condition, e.g. the application of heat, exposure to atmospheric conditions, etc. Alternatively, the film-forming polymer may form the film upon evaporation of any carrier vehicle in which the film-forming polymer may optionally be disposed. The film-forming polymer may undergo a reaction, e.g. the film-forming polymer may become cross-linked or otherwise include additional bonds, when forming the film. However, the film-forming polymer may form the film in the absence of such a reaction. The film-forming polymer may be a gelling agent. The film-forming polymer is particularly advantageous when the composition is the sunscreen, although the personal care ingredient may comprise the film-forming polymer in other compositions as well.
The substrate on which the film is formed may be any substrate, although the substrate is generally a portion of a mammal, particularly a human, as described in greater detail below with reference to the treatment method. Specific examples of suitable substrates include skin, hair, and nails.
Generally, the film is continuous, although the film may have a varying thickness. By continuous, it is meant that the film does not define any apertures. The film may be referred to as being macroscopically continuous. The film may be supported by the substrate, or may be bonded, e.g. physically and/or chemically, to the substrate. In certain embodiments, the film is optionally removable from the substrate, e.g. the film may be peelable from the substrate. The film may remain intact as a free-standing film upon being separated from the substrate or may be separated through application of shear, which may damage and/or destroy continuity of the film.
Specific examples of film-forming polymers that are suitable include acrylic polymers, silicone resins (e.g. polypropylsilsesquioxane), polyurethanes, polyurethane-acrylics, polyesters, polyester-polyurethanes, polyether-polyurethanes, polyesteramides, alkyds, polyamides, polyureas, polyurea-polyurethanes, cellulose-based polymers (e.g. nitrocellulose), silicones, acrylic-silicones, polyacrylamides, fluoropolymers, polyisoprenes, and any copolymers or terpolymers thereof or including one of these. The term “silicones,” as used herein with reference to suitable film-forming polymers, includes linear, branched, and resinous silicones, although resinous silicones are generally referred to as silicone resins rather than polymers. The silicone may be modified, e.g. the silicone may be a silicone-grafted acrylic polymer.
As introduced above, the film-forming polymer may be disposed in a carrier vehicle, which may partially or fully solubilize the film-forming polymer. Depending on a selection of the film-forming polymer, the carrier vehicle may be, for example, an oil, e.g. an organic oil and/or a silicone oil, a solvent, water, etc. The film-forming polymer may be in the form of polymer particles, which are optionally surface-stabilized with at least one stabilizer, and the polymer particles may be present as a dispersion or emulsion.
The film-forming polymer may be a block polymer, which may be styrene-free. Typically, the block polymer comprises at least one first block and at least one second block, which may be linked together via an intermediate block comprising at least one constituent monomer of the first block and at least one constituent monomer of the second block.

For example, the film-forming polymer may be generated via free-radical polymerization of at least one acrylic monomer and at least one silicone- or hydrocarbon-based macromonomer including a polymerizable end group.
Specific examples of hydrocarbon-based macromonomers include homopolymers and copolymers of linear or branched C8-C22 alkyl acrylate or methacrylate. The polymerizable end group may be a vinyl group or a (meth)acrylate group, e.g. poly(2-ethylhexyl acrylate) macromonomers; poly(dodecyl acrylate) or poly(dodecyl methacrylate) macromonomers; poly(stearyl acrylate) or poly(stearyl methacrylate) macromonomers, etc. Such macromonomers generally include one (meth)acrylate group as the polymerizable end group.
Additional examples of hydrocarbon-based macromonomers include polyolefins containing an ethylenically unsaturated end group (as the polymerizable end group), e.g. a (meth)acrylate end group. Specific examples of such polyolefins include polyethylene macromonomers, polypropylene macromonomers, polyethylene/polypropylene copolymer macromonomers, polyethylene/polybutylene copolymer macromonomers, polyisobutylene macromonomers; polybutadiene macromonomers; polyisoprene macromonomers; polybutadiene macromonomers; and poly (ethylene/butylene)-polyisoprene macromonomers.
Examples of silicone-based macromonomers include organopolysiloxanes containing the polymerizable end group, e.g. a (meth)acrylate end group. The organopolysiloxane may be linear, branched, partially branched, or resinous. In various embodiments, the organopolysiloxane is linear. In these embodiments, the organopolysiloxane may be polydimethylsiloxane, although hydrocarbon groups other than methyl groups may be present therein along with or in lieu of methyl groups. Typically, the polymerizable end group is terminal, although the polymerizable end group may optionally be pendant. One specific example of a silicone-based macromonomer is a monomethacryloxypropyl polydimethylsiloxane.
In certain embodiments, the film-forming polymer is an organic film-forming polymer that is soluble in oil as the carrier vehicle. In these embodiments, the film-forming polymer may be referred to as a liposoluble polymer. The liposoluble polymer may be of any type and specific examples thereof include those comprising or formed from olefins, cycloolefins, butadiene, isoprene, styrene, vinyl ethers, vinyl esters, vinyl amides, (meth)acrylic acid esters or amides, etc.
In one embodiment, the liposoluble polymer is formed from monomers selected from the group consisting of isooctyl (meth)acrylate, isononyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, lauryl (meth)acrylate, isopentyl (meth)acrylate, n-butyl (meth)acrylate, isobutyl (meth)acrylate, methyl (meth)acrylate, tert-butyl (meth)acrylate, tridecyl (meth)acrylate, stearyl (meth)acrylate, and combinations thereof.
Alternatively still, the liposoluble polymer may be an acrylic-silicone grafted polymer, which typically includes a silicone backbone and acrylic grafts or alternatively includes an acrylic backbone and silicone grafts.
The film-forming polymer may be halogenated, e.g. the film-forming polymer may include fluorine atoms.
Alternatively as introduced above, the film-forming polymer may be a cellulose-based polymer, such as nitrocellulose, cellulose acetate, cellulose acetobutyrate, cellulose acetopropionate or ethylcellulose. Alternatively still, the film-forming polymer may comprise a polyurethane, an acrylic polymer, a vinyl polymer, a polyvinyl butyral, an alkyd resin, or resins derived from aldehyde condensation products, such as arylsulfonamide-formaldehyde resins.

Resinous silicones generally include at least one T and/or Q unit, as understood in the art. Examples of resinous silicones include silsesquioxanes. The silicone may include any combination of M, D, T, and Q units so long as the silicone constitutes the film-forming polymer.
When the film-forming polymer comprises the silicone, the film-forming polymer may comprise an amphiphilic silicone. Amphiphilic silicones typically contain a silicone portion which is compatible with a silicone medium, and a hydrophilic portion. The hydrophilic portion may be, for example, the residue of a compound selected from alcohols and polyols, having 1 to 12 hydroxyl groups, and polyoxyalkylenes (e.g. those containing oxypropylene units and/or oxyethylene units).
The amphiphilic silicone may be an oil with or without gelling activity. Oils of this kind may comprise, for example, dimethicone copolyols, bis-hydroxyethoxypropyl dimethicone, etc.
In one embodiment, the film-forming polymer comprises a silicone organic elastomer gel. Silicone organic elastomer gels comprise linear organopolysiloxane chains crosslinked via polyoxyalkylenes. The silicone organic elastomer gel may further include hydrophilic polyether functionality pending from the linear organopolysiloxane chains. Specific examples of suitable silicone organic elastomer gels are disclosed in International (PCT) Appln. No. PCT/US2010/020110.

As introduced above, the emulsion may include various additives (e.g. those added during preparation of the emulsion), such that the emulsion itself functions as an end-use composition. However, the emulsion may also be combined with various additional components (e.g. after its preparation), such as those described above, and thus formulated into various end-use compositions, such as a personal care compositions. Such compositions may be of any form, such as a cream, gel, powder, paste, or freely pourable liquid. Compositions comprising or formed from the emulsion of the present disclosure may exhibit improved application and cosmetic properties (including reduced tackiness and stickiness), and improved clarity/low residue properties.
In some embodiments, the emulsion is itself a personal care composition, or may be formulated into a personal care composition. In such embodiments, the personal care composition may be formulated to be cosmetic, therapeutic, functional with respect to a portion of a body to which the personal care composition is applied, or some combinations thereof. Examples of personal care compositions include antiperspirants and deodorants, skin care creams, skin care lotions, moisturizers, facial treatments (e.g. acne or wrinkle removers), personal and facial cleansers, bath oils, perfumes, colognes, sachets, sunscreens, pre-shave and after-shave lotions, shaving soaps and lathers, shampoos, conditioners, hair colorants, hair relaxants, hair sprays, mousses, hair gels, permanents, depilatories, cuticle coats, make-ups, color cosmetics, foundations, concealers, blushes, lipsticks, eyeliners, mascara, oil removers, color cosmetic removers, and medicament creams, pastes or sprays (e.g. for anti-acnes, dental hygienics, antibiotics, healing promotives, etc.). In general, the personal care composition comprising the emulsion is formulated with a carrier that permits application in a conventional form, such as a liquid, rinse, lotion, cream, paste, gel, foam, mousse, ointment, spray, aerosol, soap, stick, soft solid, or solid gel, e.g. depending on the intended use. What constitutes a suitable carrier for formulating the personal care composition is readily apparent to one of ordinary skill in the art, and may be selected from those carriers exemplified herein.
The personal care composition may be in any form, either liquid or non-liquid (semi-solid, soft solid, solid, etc.). For example, the personal care composition may be a paste, a solid, a gel, or a cream. Additionally, regardless of how the emulsion was prepared, the personal care composition formed from the emulsion may itself be an emulsion, such as an oil-in-water or water-in-oil emulsion, a multiple emulsion, such as an oil-in-water-in-oil emulsion or a water-in-oil-in-water emulsion, or a solid, rigid or supple gel, including anhydrous gels. The personal care composition can also be in a form chosen from a translucent anhydrous gel and a transparent anhydrous gel. The personal care composition may, for example, comprise an external or continuous fatty phase. The personal care composition may be anhydrous. In some instances, the personal care composition can be a molded composition or cast as a stick or a dish. In specific embodiments, the personal care composition comprising the emulsion is a molded poured stick. In such embodiments, the personal care composition (e.g. in stick form) may behave as deformable, flexible elastic solid, having increased elastic softness on application.
The personal care composition comprising the emulsion can be used by any method, such as via application to a human body (e.g. skin or hair) by hand or with an applicator (e.g. a brush or sprayer). In some embodiments, the personal care composition may be intended to be removed after such application, e.g. by washing, wiping, peeling, and the like, or combinations thereof.
As mentioned above, the copolymer in general, and specific embodiments of acrylic copolymers in particular, have excellent utility when utilized in or applied as a cosmetic ingredient or film-forming agent, including for quasi-drug formulations or topical formulations. Though not limited to this particular end use application, the inventive copolymer can be utilized instead of or in combination with any conventional copolymer having a carbosiloxane dendrimer structure, which are ubiquitous in existing cosmetic formulations.
For example, the copolymer can partially or fully replace a silicone acrylate copolymer having a carbosiloxane dendrimer structure (e.g. conventional product of FA4001 CM Silicone Acrylate, FA4002 ID Silicone Acrylate, FA4003 silicone Acrylate etc.) in cosmetic formulations in following patent application publications: WO2012/143344, WO2014/154701, WO2014/154700, WO2015/092632, WO2015/097110, WO2015/097103, WO2017/050699, WO2017/050922, WO2010/026538, WO2014/087183, WO2011/051323, JP2007-320960, WO2016/030842, JP2010-018612, JP2011-016734, JP2011-016732, JP2011-016733, JP2011-016734, JP 2011-126807, JP 2011-126808, JP2013-001672, JP 2014-034568, JP 2014-040388, JP 2014-227358, JP2015-098451, JP 2015-137252, JP 2016-008200, JP2016-088848, JP 2016-121095, JP 2016-160191, JP 2018-090495, JP2000-072784, JP07-309714, JP2007-320960, JP2014-040512, WO2017/061090, JP2011-149017, JP2014-040512, JP2014-040511, WO/2018/086139, WO/2018/186138, PCT/JP18/022412, and PCT/JP18/022413.
Specific intended end use applications of the inventive copolymer are based on the cosmetic formulations of the above patent application publications, whereby a conventional copolymer having a carbosiloxane dendrimer structure of these patent application publications is replaced with the inventive copolymer of this disclosure. In certain embodiments, the inventive copolymer is utilized in combination with the conventional copolymer having the carbosiloxane dendrimer structure. In other embodiments, the inventive copolymer is utilized in lieu of (and to replace) the conventional copolymer having the carbosiloxane dendrimer structure.
Furthermore, emulsion compositions comprising copolymers can be partially or fully replaced with the inventive copolymer in emulsion. For example, copolymer emulsions in cosmetic formulations disclosed in the following documents can be replaced with emulsions comprising the inventive copolymers: WO2017/061090, WO/2018/086139, WO/2018/186138, PCT/JP18/022412, PCT/JP18/022413 and Research Disclosures: No. IPCOM000243971D, and No. IPCOM0002457480.
By replacing conventional silicone acrylate copolymer having carbosiloxane dendrimer structure with the copolymer comprising the branched organosilicon moiety in available and conventional cosmetic formulations, the skilled person in the art can anticipate and design similar or improved cosmetic formulation using the copolymer comprising the branched organosilicon moiety.
The following examples, illustrating embodiments of this disclosure, are intended to illustrate and not to limit the invention. The brief summary immediately below provides information as to certain abbreviations, shorthand notations, and components utilized in the Examples. Each group not expressly shown and pending from a silicon atom is a methyl group (—CH3) unless otherwise indicated.
“Si10” is a branched organosilicon compound having 10 silicon atoms and a propyl methacryloxy group, and is of the general formula (a) below:
“Artificial Sebum” is 3:1:1 mixed oil of triolein, oleic acid and squalane (wt./wt./wt.).
In a first beaker, 0.71 parts by weight of 90% Laureth-1 Phosphate was weighed, and then 51.68 parts by weight of ion exchanged and 0.39 parts by weight of 20% Sodium Hydroxide aqueous solution water were added and agitated to form an aqueous solution. In a second beaker, 0.60 parts by weight of 2-phenoxyethanol, 9.90 parts by weight of methyl methacrylate (MMA), 5.10 parts by weight of butyl acrylate (n-BuA), and 15.00 parts by weight of Si10 were combined and homogenized. The homogenized mixture in the second beaker was then added to the first beaker, and the contents then agitated for several minutes before being passed through a homogenizer (pressure of 300 to 400 kg/cm2) multiple times to obtain a milky white monomer emulsion without oil droplets.
In a third flask, 4.60 parts by weight of ion exchanged water and a portion of the obtained monomer emulsion were combined and heated to 80° C. while the mixture was agitated. Once the temperature reached 80° C., the rest of the obtained monomer emulsion and 7.5 parts by weight of 3% 2,2′-azobis[N-(2-carboxyethyl)-2-methylpropinamidine]tetrahydrate aqueous solution prepared with ion exchanged water were gradually added dropwise simultaneously to allow a reaction to proceed. After 3 hours, 4.5 parts by weight of 5% 2,2′-azobis[N-(2-carboxyethyl)-2-methylpropinamidine]tetrahydrate aqueous solution prepared with ion exchanged water was added. After the reaction, odor of methyl methacrylate or butyl acrylate was not noticeable. The completed emulsion has a nonvolatile content of approximately 30%, and completion of the reaction was confirmed via HPLC (SHIMAZU Prominence-i LC-2030C3D).
The above procedure was repeated using the components and proportions listed in Table 1 below to prepare the emulsions of Examples 1-3 and Comparative Example 1.
“OK” film flexibility refers to an absence of cracking noticed when bending the film.
“NG” film flexibility refers to a lack of film flexibility/a very hard film.
As shown in Table 1, the composition of the present disclosure enables the preparation of silicone acrylate copolymer emulsions with very low levels of impurities (e.g. low levels of residual Si dendrimer). The film property was also confirmed to be better than non-silicone graft acrylates.
In a first beaker, 15.20 parts by weight of methyl methacrylate (MMA), 4.80 parts by weight of butyl acrylate (n-BuA), and 20.00 parts by weight of the acrylate silicone dendrimer (Si10) were combined and mixed homogeneously to give a monomer mixture.
In a second beaker, 0.4 parts by weight of dimethyl 2,2′-azobis(2-methylpropionate) was weighed, and then charged with 21.38 parts by weight of isopropyl alcohol (IPA) and agitated to form a radical initiator solution.
In a third flask, 32.44 parts by weight of isopropyl alcohol (IPA) was charged, heated to 70° C. with agitation, and purged for 30 min via N2 bubbling to remove oxygen from the IPA. After the temperature reaches 70° C., the monomer mixture in the first beaker and the radical initiator solution in the second beaker were gradually added dropwise simultaneously. Once the addition was complete, 6.18 parts by weight of isopropyl alcohol was used to rinse the first and second beakers into the third, and the reaction allowed to proceed for 10 hours at 70° C. The IPA was then replaced with isododecane (IDD) by 110° C. heating in vacuo (50 mmHg vacuum) to give a polymer solution with a nonvolatile content of approximately 40%. Residual Si dendrimer was determined by HPLC (SHIMAZU Prominence-i LC-2030C3D).
The above procedure was repeated using the components and proportions listed in Table 2 below to prepare the compositions of Example 4 and Comparative Example 2.
“OK” film flexibility refers to an absence of cracking noticed when bending the film.
The terms “comprising” or “comprise” are used herein in their broadest sense to mean and encompass the notions of “including,” “include,” “consist(ing) essentially of,” and “consist(ing) of. The use of “for example,” “e.g.,” “such as,” and “including” to list illustrative examples does not limit to only the listed examples. Thus, “for example” or “such as” means “for example, but not limited to” or “such as, but not limited to” and encompasses other similar or equivalent examples.
Generally, as used herein a hyphen “-” or dash “-” in a range of values is “to” or “through”; a “>” is “above” or “greater-than”; a “≥” is “at least” or “greater-than or equal to”; a “<” is “below” or “less-than”; and a “≤” is “at most” or “less-than or equal to.” On an individual basis, each of the aforementioned applications for patent, patents, and/or patent application publications, is expressly incorporated herein by reference in its entirety in one or more non-limiting embodiments.
It is to be understood that the appended claims are not limited to express and particular compounds, compositions, or methods described in the detailed description, which may vary between particular embodiments which fall within the scope of the appended claims. With respect to any Markush groups relied upon herein for describing particular features or aspects of various embodiments, different, special, and/or unexpected results may be obtained from each member of the respective Markush group independent from all other Markush members. Each member of a Markush group may be relied upon individually and or in combination and provides adequate support for specific embodiments within the scope of the appended claims.
Further, any ranges and subranges relied upon in describing various embodiments of the present invention independently and collectively fall within the scope of the appended claims, and are understood to describe and contemplate all ranges including whole and/or fractional values therein, even if such values are not expressly written herein. One of skill in the art readily recognizes that the enumerated ranges and subranges sufficiently describe and enable various embodiments of the present invention, and such ranges and subranges may be further delineated into relevant halves, thirds, quarters, fifths, and so on. As just one example, a range “of from 0.1 to 0.9” may be further delineated into a lower third, i.e., from 0.1 to 0.3, a middle third, i.e., from 0.4 to 0.6, and an upper third, i.e., from 0.7 to 0.9, which individually and collectively are within the scope of the appended claims, and may be relied upon individually and/or collectively and provide adequate support for specific embodiments within the scope of the appended claims. In addition, with respect to the language which defines or modifies a range, such as “at least,” “greater than,” “less than,” “no more than,” and the like, it is to be understood that such language includes subranges and/or an upper or lower limit. As another example, a range of “at least 10” inherently includes a subrange of from at least 10 to 35, a subrange of from at least 10 to 25, a subrange of from 25 to 35, and so on, and each subrange may be relied upon individually and/or collectively and provides adequate support for specific embodiments within the scope of the appended claims. Finally, an individual number within a disclosed range may be relied upon and provides adequate support for specific embodiments within the scope of the appended claims. For example, a range “of from 1 to 9” includes various individual integers, such as 3, as well as individual numbers including a decimal point (or fraction), such as 4.1, which may be relied upon and provide adequate support for specific embodiments within the scope of the appended claims.
The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Obviously, many modifications and variations of the present invention are possible in light of the above teachings. The invention may be practiced otherwise than as specifically described.
