Method for preparing light-absorbing polymeric compositions

BACKGROUND OF THE INVENTION

[0002] This invention relates to an improved method for preparing light-absorbing polymeric compositions, which are useful as powders or pellets for incorporation into a variety of thermoplastic resins such as cellulose esters, polyesters, polyolefins, polycarbonates, polyamides, etc. by conventional melt or solution blending techniques. The colored thermoplastic resins thus produced have good clarity, good color development, excellent fastness to light and are useful for a variety of end uses where nonhazardous, nonmigrating, or nonextractable colorants are needed.

[0003] It is well-known that thermoplastic polymers may be colored by adding pigments or solvent dyes (e.g., see Thomas G. Weber, Editor, Coloring of Plastics, John Wiley & Sons, New York, 1979). The use of pigments, however, is accompanied by undesirable properties such as opacity, dullness of color, low tintorial strength, etc. Also, difficulties in uniformly blending the in soluble pigments with the thermoplastic resin are often encountered. Also useful for coloring thermoplastic polymers are the solvent dyes (K. Venkataraman, Editor, The Chemistry of Synthetic Dyes, Vol. 8, Academic Press, New York, 1978, pp. 81-131), which provide compositions having improved clarity, brightness in hue and high tinctorial strength, but which may lead to dye migration, extraction, etc. from the colored thermoplastic polymer. These problems are of particular concern when solvent dyes are used to color flexible polymers such as polyvinyl chloride, polyethylene and polypropylene which have low glass transition temperatures.

[0004] Plastics, paints, printing inks, rubber, cosmetics, and similar materials are typically colored by organic pigments when superior brilliance and tinctorial strength are important. Toxicity considerations have presented chronic problems relative to the use of organic pigments since some have been shown to be potential carcinogens and to cause contact dermatitis.

[0005] Plastics are also colored by using color concentrates consisting of physical admixtures of polymers and colorants (usually solvent dyes). However, the use of such physical admixtures to color polymeric materials such as polyester, e.g., poly(ethylene terephthalate) and blends thereof, present a number of problems, including:

[0006] Colorant migration during drying of the colored polyester pellets.

[0007] Colorant migration during extrusion and colorant accumulation on dies which can cause shutdowns for clean-up. Such colorant migration and accumulation result in time consuming and difficult clean-up, particularly when a polymer of another color is subsequently processed on the same equipment.

[0008] Colorants may not mix well, for example, when using two or more color cencentrates to obtain a particular shade.

[0009] Colorants may diffuse or exude during storage and use of the colored polymeric material.

[0010] The colored polymeric compositions which are prepared by the process of this invention eliminate or minimize the aforementioned problems associated with the use of conventional dyes and pigments.

PRIOR ART

[0011] To attempt to overcome some of the problems mentioned above, particularly as relates to coloring polyesters, colored polyester compositions have been prepared by copolymerizing relatively low amounts of monomeric colorants during the polymer preparation (U.S. Pat. Nos. 5,194,571; 5,106,942; 5,102,980; 5,032,670; 4,892,922; 4,740,581; 4,403,092; 4,359,570; 4,267,306 and W092/07913). However, the preparation of these colored polymers require dyes having outstanding thermal stability since the colorants are exposed to very high temperatures for prolonged periods of time necessary for polyester formation, thus severely circumscribing the selection of efficacious colorants. For example, only the nonazo type colorants have been shown to have the adequate thermal stability for copolymerization into polyesters, since azo type compounds do not have the resquite thermal stability for copolymerization.

[0012] Furthermore, it is known to prepare polymeric dyes by reacting dyes containing reactive hydroxy and amino groups with organic di-acid chlorides in solvents (U.S. Pat. Nos. 2,994,693; 3,403,200; 4,619,990; 4,778,742; 5,401,612). Although this method of polymer preparation allows the use of a wide range of chromophoric classes, including azo compounds, as colorant monomers, the polymerization reaction in each case involves the use of very reactive organic di-acid chlorides which are toxic and involve difficult to handle inorganic halogen compounds in their preparation and have accompanying problems of hydrolysis in the presence of water which causes serious handling and storage problems. The hydrolysis product (HCl) is particularly corrosive and makes storage of these compounds difficult. Furthermore, since the di-acid chlorides will react with water, the monomeric dyes must be specially dried to avoid side reactions in the polymer preparation.

[0013] In a similar attempt to prepare polymeric dyes using relatively low temperatures, polyurethanes have been prepared by reacting dyes bearing two hydroxyalkyl group with aliphatic and aromatic isocyanates (U.S. Pat. No. 5,194,463). However, the organic isocyanates themselves are extremely toxic and present difficult handling problems. They also are reactive with water and thus the reaction requires specially dried monomeric dyes. Also, the colored polyurethanes as a class do not have excellent thermal stability.

[0014] It is further known to prepare colored condensation polymers by reacting a polymerizable lactone or a hydroxyalkanoic acid with a dye containing reactive hydroxy group (U.S. Pat. No. 4,933,426). The procedure again requires relatively high reaction temperatures and prolonged times and use a large excess of the lactone reactant. The method is further hindered by the fact that some lactones are suspected carcinogens.

[0015] Light-absorbing polymeric compositions have also been produced by free radical polymerization of vinyl functionalized light-absorbing monomers (U.S. Pat. Nos. 5,310,837; 5,334,710; 5,359,008; 5,434,231 and 5,461,131).

[0016] Finally, it is known that one may color plastics, in particular polyolefins, with low melting, cross-linked colored polyester compositions containing residues of terephthalic acid, isophthalic acid, or both, a low-molecular weight trimethylol alkane, i.e., 1,1,1-trimethylol propane and a copolymerizable colorant, said colorant being present at a level of 0.1-25% by weight (U.S. Pat. No. 4,116,923). Difficulties are encountered, however, in preparing these highly cross-linked colored polymers as extreme care with regard to the temperature, amount of vacuum, the level of colorant present, and the reaction time, is necessary in order to attempt to reproduce the same quality of cross-linked colored polyester composition. Further, these colored polyester compositions are brittle or low melting and may cause deterioration in physical properties of themoplastic polymers when added in quantities sufficient to produce a high level of coloration.

[0017] Practice of the Invention

[0018] This invention relates to a method for preparing a light absorbing linear polymeric having Formula I

[0019] wherein A comprises the residue of a diacidic monomer comprising about 1 to 100 mole % of at least one light-absorbing monomer having a light absorption maximum between about 300 nm and about 1200 nm and wherein the remaining portion of A comprises the residue of a non-light absorbing monomer which does not absorb significantly at wavelengths above 300 nm or has a light absorption maximum below 300 nm and wherein B is a divalent organic radical selected from C2-C12 alkylene, C3-C8 cycloalkylene, C1-C4 alkylene- C3-C8-cycloalkylene- C1-C4 alkylene, C1-C4 alkylene-arylene- C1-C4 alkylene, C2-C4 alkylene-O— C2-C4 alkylene, and C2-C4-alkylene-L-arylene- C2-C4 alkylene and C2-C4 alkylene- (L-C2-C4 alkylene)1-4, wherein L is a linking group selected from-O—, —S—, —SO2—, —NH—, —N(C1-C6alkyl)-, —N(aryl)-, —N(SO2 C1-C6 alkyl)-, —N(SO2aryl)-, —SO2N(C1-C6 alkyl)- and combinations thereof; wherein n is at least 2.

[0020] The process comprises reacting said diacidic monomer with an organic compound of Formula II

H—Y1—H IV

[0023] wherein H represents an acidic hydrogen atom; Y1 is a divalent moiety, selected from-O2C—R1—CO2— and-O—R2—O-and-O2C—R3—O—, wherein R1 is selected from C2-C12 alkylene, 1-4-cyclohexylene, arylene, arylene-O-arylene, arylene-S2-arylene, arylene-S-arylene, and C1-C4 alkylene-O—C1-C4 alkylene; wherein R2 is selected from arylene, arylene-O-arylene, arylene-S-arylene, arylene-SO2-arylene, phenylene-phenylene, and phenylene-C(R4)2-phenylene; wherein R4 is selected from hydrogen and C1-C4 alkyl; wherein R3 is selected from arylene.

[0024] In diacid light absorbing monomers having Formula III, the hydrogen atoms are preferably attached to an oxygen, a sulfur or a nitrogen atom which in combination provides two acidic functional group which can produce the corresponding anions under basic conditions by removal of the protons. The acidic functional groups usually have an acid dissociation constant of about 10−15 to about 10−12 (pKa of from about 1.5 to about 12). In the case of nitrogen, both protons may be attached to a single nitrogen which is attached to a sulfonyl moiety thus providing two acidic hydrogens on a single functional group.

[0025] Typical, acidic groups which provide one acidic hydrogen include-CO2H, —SH, —OH attached to an aromatic ring, —CONHCO—, —SO2—NH—CO—, —SO2—NH—SO2—, 1(H)-1,2,4-triazol-3-yl-, imidazolyl, benzimidazolyl, pyrazolyl, —SO2H attached to aromatic ring, —NHSO2R5 and-SO2NHR5, wherein R5 is selected from C1-C6 alkyl; C1-C6 alkyl substituted with at least one group selected from C1-C6 alkoxy, aryl, aryloxy, arylthio or C3-C8 cycloalkyl; C3-C8 cycloalkyl; aryl.

[0026] An example of an acidic functional group providing two acidic hydrogen attached to nitrogen is the sulfamoyl group (—SO2NH2).

[0027] The preferred method for producing light absorbing polymeric compositions utilizes the monomers of Formula III, wherein the protons are a part of the-CO2H, OH attached to aromatic ring, —CO—NH—CO— or 1(H,)-1,2,4-triazol-3-yl functional groups. The carboxy groups are normally attached to an aromatic ring carbon or aliphatic carbon which is a part of Y. The hydroxy groups are normally attached to an unsubstituted or substituted phenyl or naphthyl radical which is a part of Y. The —CO—NHCO— groups are usually attached to an aromatic ring to provide an imide such as phthalimide or naphthalimide which are a part of Y. The 1(H)-1,2,4-triazol-3-yl group has the following Formula V, wherein R5′ is

[0028] selected from hydrogen, C1-C6 alkyl or aryl. It should be observed that the triazole may exist in isomeric form as follows:

[0029] The 1(H)-1,2,4-triazol-3-yl group is preferably attached to a sulfur atom which is attached to the remainder of Y.

[0030] The method of the invention in the broadest sense involves the preparation of light absorbing polymeric compositions by reacting a diacidic monomer comprising at least 1 mole % of at least one diacidic light absorbing monomer represented by H-A-H with an organic compound containing two reactive groups represented by X—B—X1, where B, X and X1 are as defined above. Thus, the method may be summarized as:

[0031] The diacidic monomer H-A-H must be acidic enough to form two nucleophiles in the presence of base under convenient reaction conditions for the most advantageous process. This usually requires that diacidic monomers have pKa values of about 12 or below.

[0032] The dinucleophilic monomer, formed by the removal of the two hydrogen atoms by the base, attacks the electrophilic compound II, thus displacing anions X− and X1−, with head-to-tail combination with covalent bonding to produce a linear polymer &Brketopenst;A-B&Brketclosest;n, wherein n represents the number of repeating units. The number of repeating units must be at least 2, but usually ranges between about 2 and about 25, with the preferred number being between about 3 and about 15.

[0033] The composition produced by the method of the invention comprises, as stated above, a polymer having the general formula &Brketopenst;A-B&Brketclosest;n. The composition also comprises one or more cyclic compounds having the general formula

[0034] wherein m may be 1, 2, 3, or 4, e.g., the cyclic compounds having the general structures:

[0035] The number and concentrations of the cyclic compounds is dependent upon a variety of factors such as the structure of diacid H-A-H, the structure of the organic compound X—B—X1, and the conditions used to facilitate the reaction to produce the composition. The cyclic compounds may constitute up to about 35 weight percent, typically about 0.5 up to 30 weight percent, of the total weight of the composition produced by the method of the invention.

[0036] Suitable bases include alkali metal carbonates; alkali metal bicarbonates; tertiary amines such as triethylamine, tri-n-butylamine, N-methylpiperidine, N,N′-dimethylpiperazine, N-methylmorpholine, N,N,N′,N′-tetramethylenediamine, etc.; aromatic nitrogen bases such as pyridines, picolines, quinolines, isoquinolines, N-alkylpyrroles, N-alkylimidazoles, etc.; bicyclic nitrogen containing bases having non-hindered electron pairs, such as 1,8-diazabicyclo[4,3,0]undec-7-ene (DBU), 1,5-diazabicylco[4,3,0]non-5-ene (DBN) and 1,4-diazadicyclo[2,2,2]octane (DABCO®).

[0037] Typical solvents useful in the polymerization reaction include aprotic polar solvents such as N,N-dimethylacetamide, N,N-dimethylformamide, N-methyl-2-pyrrolidone, N-methyl-N-phenyl formamide, dimethyl sulfoxide, aliphatic nitriles, sulfolane, hexamethyl phosphoramide, etc. and mixtures thereof. Water, alcohols, ketones pyridine and ether-alcohols, such as the Cellosolves, also are sometimes useful. One requirement is that the solvent not form a stronger nucleophile in the presence of the base than that obtained from the diacidic monomer H-A-H.

[0038] The new improved process of the invention allows the preparation of near ultraviolet (UV-A, UV-B and UV-C), visible and near infrared light absorbing linear polymeric compositions at relatively low temperatures, usually at from about 75° C. to about 125° C., without prolonged heating times. Furthermore, the method is adaptable to batch-process production which is advantageous for expensive products such as colorants, near infrared absorbers and near ultraviolet absorbers. The method is adaptable to a wide range of chromophoric classes since the polymer preparative reaction is carried out at relatively low temperature, which for example, allows colored polymeric compositions to be readily prepared from the very important azo class of colorants.

[0039] The preferred reactants of Formula II

X—B—X1

[0040] are the disulfonate compounds where X and X1 are both a sulfonate ester of the formula-OSO2R, wherein R is selected from C1-C4 alkyl, phenyl or p-methylphenyl and wherein B is selected from C2-C6 alkylene, —CH2-1,4-cyclohexylene-CH2—, 2,2,4,4-tetramethyl-1,3-cyclobutylene, 1,4-cyclohexylene, —CH2CH2(OCH2CH2)2-3 and —CH2CH2O-1,4-phenylene-O—CH2CH2—. Particularly, preferred reactants of Formula II are those where B is selected from-CH2CH2—, —CH2CH(CH3)CH2—, —CH2C(CH3)2CH2—, —(CH2)4—, —(CH2)6—, —CH2CH2(OCH2CH2&Parenclosest;1-4 and-CH2-1,4-cyclohexylene-CH2—.

The above-described light absorbing composition of formula Ia also contains or comprises one or more cyclic compounds having the formula

[0044] wherein A1 and B are defined above and m may be 1, 2, 3, or 4. As stated hereinabove, the number and concentrations of the cyclic compounds is dependent upon a variety of factors such as the structure of diacid H-A-H, the structure of the organic compound X—B—X1, and the conditions used to facilitate the reaction to produce the composition. The cyclic compounds of formula I-B may constitute up to about 35 weight percent, typically about 1 up 30 weight percent, of the total weight of the above-described light absorbing composition.

[0045] The invention also relates to a light absorbing linear polymeric composition having Formula Ib

[0046] wherein A2 comprises the residue of at least one diacidic monomer, having a light absorption maximum between about 300 nm and about 1200 nm, preferably between about 325 nm and 1100 nm and most preferably between about 350 nm and 1000 nm and which comprises at least about 50% by weight of the total of the composition of Formula Ib and wherein the remainder of A2 comprises the residue of at least one non-light absorbing monomer of Formula IV above, and wherein said polymeric composition has been prepared by reacting diacidic monomers of Formula III and Formula IV with an organic compound having Formula II above, with the polymer producing reaction having been carried out in a solvent in the presence of base. The light absorbing composition of formula Ib also contains or comprises one or more cyclic compounds having the formula

[0047] wherein A2 and B are defined above and m may be 1, 2, 3, or 4. Again, the number and concentrations of the cyclic compounds is dependent upon a variety of factors such as the structure of diacid H-A-H, the structure of the organic compound X—B—X1, and the conditions used to facilitate the reaction to produce the composition. The cyclic compounds of formula I-B may constitute up to about 35 weight percent, typically about 1 up 30 weight percent, of the total weight of the above-described light absorbing composition.

[0048] The polymer compositions of Formula I, Ia, and Ib and the cyclic compositions of formulas I-A, I-B and I-C are referred to as “polydyes” herein when they absorb visible light thus rendering them strongly colored.

[0049] The invention further relates to a thermoplastic polymeric composition which comprises a thermoplastic polymer blended with at least one light absorbing linear polymeric composition of Formula I, Ia or Ib above which, as noted above, contain or comprise one or more cyclic compounds having the general formula I-A. The thermoplastic polymeric composition is usually selected from polyesters, polyolefins, polyamides, polyimides, polyvinyl chloride, polyurethanes, polycarbonates, cellulose esters, polyacrylates, polyvinylesters, polyester-amides, polystyrene, polyacrylonitrile- butadiene- styrene and polystyrene-acrylonitrile. The preferred thermoplastic polymeric composition comprises the light-absorbing polymeric compositions of Formula Ia.

[0096] Typical active methylene compounds useful in the preparation of methine, arylidene, polymethine, azamethine and azo-methine compounds corresponding to Formulae VIII, VIIIa, VIIIb, IX and XIII, respectively, are disclosed in the literature, e.g. U.S. Pat. Nos. 4,338,247; 4,617,373; 4,617,374; 4,707,537; 4,749,774; 4,826,903; 4,845,187; 4,950,732; 4,981,516 and 5,283,326.

[0097] According to the present invention the light-absorbing polymeric and cyclic compositions are incorporated into a wide variety of thermoplastic polymers using conventional techniques, e.g. solution or melt blending, such as those employed to incorporate other additives in such polymers (see R. Gächter and H. Müeller, Editors: Plastics Additives Handbook, Hansu Publishers, New York, 1985, pp. 507-533; 729-741). For example, the light absorbing polymeric and cyclic compositions may be dry blended in the form of pellets or powders with or without adhesion promoters or dispersing agents. This premix can be subsequently processed on extruders or injection molding machines. Other conventional additives such as plasticizers, nucleating agents, flame retardants, lubricants, etc. may also be present in the final thermoplastic composition.

[0098] A wide range of thermoplastic polymers useful for blending with the light absorbing polymeric and cyclic compositions are known in the art and includes the homopolymers, copolymers and blends of polyesters, e.g., poly(ethylene terephthalate); polyolefins, e.g., polypropylene, polyethylene, linear low density polyethylene, polybutylene, and copolymers made from ethylene, propylene and/or butylene; copolymers from acrylonitrile, butadiene, and styrene; copolymers from styrene and acrylonitrile; polyamides, e.g., Nylon 6 and Nylon 66; polyvinyl chloride; polyurethanes; polyvinylidene chloride; polycarbonates; cellulose esters, e.g., cellulose acetate, propionate, butyrate, or mixed esters; polyacrylates, e.g., poly(methyl methacrylate); polyimides; polyester-amides; polystyrene; and mixtures or blends thereof etc.

[0099] It should also be appreciated that a multiplicity of colors may be obtained by combining individual colors, e.g., subtractive colors such as yellow, magenta and cyan according to known color technology (see N. Ohta, Photographic Science and Engineering. Volume 15, No. 5, September-October 1971, pp. 395-415).

[0100] The particular chromophore groups present will, of course, determine the color (hue+value+chroma) of the colored polymer composition and finally the color (hue+value+chroma) of the thermoplastic polymer blends of the present invention. A large gamut of colors may be obtained, as noted above.

[0101] The actual amount of the light absorbing polymers used in combination with thermoplastic polymer will depend upon the inherent tinctorial strength of the chromophore used to prepare the light absorbing polymer, the mole % of the light absorbing monomer used to prepare the light absorbing polymer and the required level of light absorption necessary to achieve a certain property. Typically, the amount of light-absorbing polymer added to the thermoplastic polymer is such that the total amount of light-absorbing polymer in the final thermoplastic blend is from about 0.001% by weight to about 20% by weight, preferably from about 0.01% by weight to about 10% by weight. The final thermoplastic polymer blends thus provided are useful as a variety of molded and extruded articles, including thick and thin plastic films, plastic sheeting, molded plastic articles, containers and fibers, and the like.

[0102] When the light-absorbing polymeric compositions absorb visible light they may be used to impart light or heavy shades of a variety of colors to thermoplastics. Certain compounds which possess unique visible light-absorbing properties are useful also as toners in imparting a desirable neutral to slightly blue hue to polyesters having a yellow appearance as described in U.S. Pat. No. 5,384,377, which discloses the copolymerization of certain thermally stable colorants for this purpose during polyester manufacture. Some of the infra-red absorbing polymeric and cyclic compositions are useful in imparting invisible markings to thermoplastics as described in U.S. Pat. No. 5,461,136, wherein the infrared absorbing compounds are fluorescent in the near infrared and are copolymerized into the thermoplastic condensation polymer during manufacture. The ultra violet absorbing polymeric and cyclic compositions may be used to impart ultra violet (UV) light screening properties to the thermoplastics; to serve as optical brighteners for the thermoplastics or to serve as UV stabilizers for the polymers themselves or for other light absorbers such as colorants.

[0103] The weight average molecular weights (Mw) and the number average molecular weights (Mn) of the polymeric compositions were determined using gel permeation chromatography (GPC) analysis.

[0104] The following examples illustrate further the practice of the invention.

EXAMPLE 1

The reaction mixture was poured into methanol (600 mL) with stirring. The yellow polymeric product was collected by filtration and washed with methanol until filtrate was essentially clear. The methanol-wet filter cake was slurried in 1.0 L of water, the mixture acidified by the addition of acetic acid and the yellow product was collected by filtration, washed with hot water and dried in air (yield- 21.16 g). By gel permeation chromatography (GPC) the polymeric product has a weight average molecular weight of 6,083, and number average molecular weight of 3,000 and a polydispersity value of 2.03.

Example 537

[0340] To dimethylfomamide (DMF, 45.0 mL) was added 1,5-bis(2-carboxyphenyl-thio)anthraquinone (17.9 g, 0.035 mole). The mixture was stirred for about 10 minutes and then 1,8-diazabicyclo [5,4,0]undec-7-ene (DBU, 10.4 g, 0.068 mole) was added followed by 1,2-ethanediol, dimethanedisulfonate (7.64 g, 0.035 mole) and additional DMF (10.0 mL). The reaction mixture was stired at about 110° C. for 3.0 hours and allowed to cool to about 55° C. Methanol (35.0 g) was added dropwise with stirring followed by water (20 mL) and acetic acid (3.0 mL). The yellow solid was collected by filtration, washed with methanol (25 mL), warm water (50 mL) and then finally with methanol to facilitate drying. The yield of polymeric and cyclic yellow product was 18.2 g.

Examples 538-543

[0341] The procedure described in Example 537 was repeated exactly except that the reactant X-B-X1 used in each example was as follows:

[0342] Example 538: 1,3-propanediol, dimethanedisulfonate

[0343] Example 539: 1,4-butanediol, dimethanedisulfonate

[0344] Example 540: diethylene glycol, dimethanedisulfonate

[0345] Example 541: 1,6-hexanediol, dimethanedisulfonate

[0346] Example 542: 1,4-cyclohexanedimethanol, dimethanedisulfonate

[0347] Example 543: 1,12-dodecanediol, dimethanedisulfonate

[0348] The weight yields (Weight, g), percent yields (Yield), weight average molecular weights (Mw), number average molecular weights (Mn), and polydispersities (Mw/Mn, by GPC) for each of the light absorbing (yellow) compositions prepared in Examples 537-543 are presented in Table 24.

[0349] The percent yields were calculated by dividing the actual weight of the polymer

&Brketopenst;A−&Brketclosest;n

[0350] obtained in grams by the theoretical number of moles of repeating unit multiplied by the gram molecular weight of the repeating unit and then multiplying the number thus obtained by 100.

[0351] The approximate amount of cyclic compounds of formula I-A present in each of the light absorbing compositions produced in Examples 537-543 was determined by a combination of GPC, NMR and FDMS analyses. The weight percentages of the cyclic compounds having the structure

582

[0352] wherein m is 1, 2, 3, or 4 present in the compostiion of Examples 537-543 is set forth in Table 25. The remainder or balance of the light absorbing compositions was presumed to be a linear polymer.
