Description

BACKGROUND OF THE INVENTION

The present invention relates to new acrylates carrying at least two functional groups chosen from the alcohol, aldehyde and ether functional groups, to a process for their manufacture and to the production of new polymers and copolymers from the said acrylates.

U.S. Pat. No. 3,743,669 discloses a process for the preparation of acrylic compounds of formula ##STR2## by reaction in a liquid phase at a temperature approximately from 0.degree. to 200.degree. C. of an .alpha.,.beta.-olefinically unsaturated carboxylic acid derivative of formula CH.sub.2 .dbd.CHY with an aldehyde of formula RCHO, Y being chosen from ##STR3## each of R.sup.1 to R.sup.4 denoting an alkyl (C.sub.1 -C.sub.12), cycloalkyl (C.sub.5 -C.sub.12), aryl, aralkyl or alkaryl, and R denoting alkyl (C.sub.1 -C.sub.8), alk-(C.sub.1 -C.sub.4)aryl, aralkyl (C.sub.1 -C.sub.4) or aryl, the said reaction being carried out in the presence of a catalytic quantity of a cyclic tertiary amine containing at least one nitrogen atom common to three rings. This reaction is very slow at room temperature. Thus, the reaction of 7.9 moles of acetaldehyde and 5.27 moles of ethyl acrylate at room temperature in the presence of 0.26 moles of diazabicyclo[2,2,2]-octane produces 93% of ethyl 2-(1-hydroxyethyl)acrylate only after 7 days. The same reaction carried out at 120.degree.-124.degree. C. takes place with a conversion of 82% at the end of 8 hours, but at the expense of selectivity. Furthermore, the Assignee Company has found that this reaction does not occur, even after 10 days, with some aldehydes whose carbonyl group is sterically hindered, such as trimethylacetaldehyde.

Bearing in mind the special behaviour which may be expected of acrylates containing a hydroxyl group in their structure, the Assignee Company has been concerned with obtaining new acrylates by functionalisation by means of dialdehydes.

SUMMARY OF THE INVENTION

A first subject of the present invention consists, therefore, of new acrylates chosen from those of ##STR4## those of formula ##STR5## those of formula ##STR6## in which: R is a radical chosen from alkyl radicals containing from 1 to 12 carbon atoms, cycloalkyl radicals containing from 5 to 12 carbon atoms, and aryl, arylalkyl and alkylaryl radicals,

Y is a radical chosen from alkylene radicals containing from 1 to 12 carbon atoms, arylene radicals containing from 6 to 12 carbon atoms, heterocyclic radicals whose ring contains from 5 to 12 members and whose heteroatom is chosen from nitrogen, oxygen and sulphur, and alkylarylene radicals in which the alkyl part contains from 1 to 4 carbon atoms, and Y not being able to denote 1,4-phenylene when R denotes methyl, Z is a hydrocarbon radical containing at least two carbon atoms forming with the oxygen and the two adjacent carbons a ring containing from 4 to 8 members and preferably containing 5 or 6 members.

As examples of radicals R there may be mentioned especially the methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, phenyl and benzyl radicals. As examples of radicals Y there may be mentioned the radicals (CH.sub.2).sub.n in which n is an integer ranging from 4 to 12, phenylene (ortho, meta, para) radicals C.sub.6 H.sub.4, 3,3'-diphenyl and 4,4'-diphenyl radicals, the 2,5-thiophenyl radical and the 2,5-furyl radical.

As examples of radicals Z there may be mentioned especially the radicals (CH.sub.2).sub.2 and (CH.sub.2).sub.3 and the phenylene radical C.sub.6 H.sub.4.

A second subject of the present invention consists of a process for the preparation of the acrylates of formulae (I) to (III). Although a common feature of the preparation of all these compounds is a stage involving an acrylate derived from an alcohol ROH and a dialdehyde, their synthesis nevertheless exhibits special features, depending on whether monoacrylates of formulae (I) and (III) or else diacrylates of formula (II) are involved. This is why the process of preparation according to the invention will now be described with reference to each of the classes of compounds according to the invention.

The preparation of the acrylates of formula (I) to (III) is carried out by reacting an acrylate of formula: ##STR7## in which R is defined as above with a dialdehyde of formula ##STR8## in which Y is defined as above, in the presence of an effective quantity of at least one functionalisation catalyst. As a functionalisation catalyst which is suitable for the reaction with an aldehyde there may be mentioned especially relatively strong bases such as cyclic tertiary amines containing at least one nitrogen atom common to three rings, described in U.S. Pat. No. 3,743,669, for example diazabicyclo[2,2,2]octane, quinuclidine and .alpha.-quinuclidinol. An effective quantity of functionalisation catalyst obviously depends on the nature of the latter, but also on the acrylate of formula (IV) and the aldehyde of formula (V). It is generally approximately between 2 and 20%, preferably approximately between 4 and 10 mol % relative to the sum of the reactants present - acrylate and dialdehyde.

As an example of dialdehydes of formula (V) there may be mentioned especially terephthalaldehyde, isophthalaldehyde, orthophthalaldehyde, glutaraldehyde, hexanedial, decanedial, dodecanedial, thiophene-2,5-dicarboxyaldehyde, furan-2,5-dicarboxaldehyde, 3,3'-biformyldiphenyl and 4,4'-biformyldiphenyl.

The process of preparation according to the invention can be additionally carried out in the presence of at least one electrophilic activator such as lithium chloride or fluoride in a quantity which may be up to approximately 5 mol % relative to the sum of the reactants present - acrylate and dialdehyde.

The process according to the invention may be additionally carried out in the presence of an organic solvent such as tetrahydrofuran, methylene chloride, chloroform, dioxane, acetonitrile, methyl ethyl ketone, ethanol, ethyl acetate and the like.

To make use of the process according to the invention a temperature of between 15.degree. C. and 125.degree. C. may be chosen, preferably approximately between 20.degree. C. and 50.degree. C., and not exceeding the boiling temperature of the solvent when a solvent is employed.

The reactants may be present in the reaction medium in any concentration. However, for reasons of kinetics it is generally preferable to avoid an excessively high dilution with the solvent and to conform to an acrylate/dialdehyde molar ratio of approximately between 0.2 and 10. The possible excess of one of the two reactants in relation to the other enables it then to act as a solvent.

Finally, the reaction according to the invention may be carried out in the presence of an effective quantity of at least one polymerisation inhibitor. As examples of polymerisation inhibitors which can be employed there may be mentioned especially phenothiazine, hydroquinone methyl ether, N,N-diethylhydroxylamine, nitrobenzene, di-tert-butylcatechol, hydroquinone, p-anilinophenol, di(2-ethylhexyl)octylphenyl phosphite, 2,5-di-tert-butyl-4-hydroxytoluene, methylene blue and their mixtures in all proportions. An effective quantity of polymerisation inhibitor is generally between 0.05% and 0.5% by weight of acrylic compound.

Although atmospheric pressure is generally satisfactory, the process according to the invention can also be used under pressure.

Depending on whether it is desired to direct the reaction according to the invention towards the production of monoacrylates of formulae (I) and (III) or else towards the production of diacrylates of formula (II), some special conditions must, nevertheless, be obeyed. In fact, the reaction according to the invention generally produces a mixture of a monoacrylate and of a diacrylate which must then, at a time chosen for stopping the reaction, be separated by a conventional separation technique. In some cases, the separation is facilitated by the difference in physical state between the two compounds formed, at normal pressure and temperature. Thus, for example, in the case of terephthalaldehyde, the monoacrylate formed is a liquid, whereas the diacrylate formed is a white solid. As already mentioned elsewhere, the monoacrylates of formula (III) are formed in preference to the monoacrylates of formula (I) when the dialdehyde of formula (V) which is employed for the reaction according to the invention is of a structure such that a cyclisation incorporating one of the oxygen atoms of the dialdehyde can easily take place. Such a possibility is particularly favourable when Y is a (CH.sub.2).sub.2 or (CH.sub.2).sub.3 radical or else a phenylene radical C.sub.6 H.sub.4 on which the aldehyde functional groups are situated in the ortho position.

The composition of the mixture of monoacrylate and diacrylate which is formed by the reaction according to the invention is affected in a complex manner by a set of parameters such as:

the reaction time, it being possible for the latter to range from approximately 1 hour to approximately 12 days, depending on the reaction temperature and pressure which are chosen; the monoacrylate is generally formed first, in a virtually quantitative manner, after a relatively short time, of the order of a few hours at room temperature; in a second stage the monoacrylate disappears progressively, to form the diacrylate; the nature of the solvent employed: all conditions being otherwise equal, the diacrylate is formed much more easily in tetrahydrofuran or methylene chloride than in chloroform; the quantity of solvent employed: dilution with a solvent such as tetrahydrofuran slows down the first stage of formation of the monoacrylate and, to a still much greater extent, the second stage of formation of the diacrylate; the quantity of functionalisation catalyst employed: all conditions being otherwise equal, an increase in the quantity of catalyst results in a slight acceleration of the monoacrylate formation stage and in a more pronounced acceleration of the diacrylate formation stage; the acrylate/dialdehyde molar ratio: in the presence of solvent and at constant total volume, that is to say apart from the dilution effect, an increase in this ratio produces the acceleration of the diacrylate formation; the reaction temperature: all conditions being otherwise equal, an increase in the temperature is reflected in a faster formation of the diacrylate.

The new acrylates according to the invention can polymerise or copolymerise with other ethylenically unsaturated monomers such as ethylene, as well as:

an alkyl acrylate or methacrylate in which the linear or branched alkyl group, optionally substituted, for example, with at least one halogen atom such as chlorine or fluorine and/or by at least one hydroxyl group, contains from 1 to 20 carbon atoms, an aryl acrylate or methacrylate such as benzyl methacrylate, a vinylaromatic hydrocarbon such as styrene, vinyltoluene, .alpha.-methylstyrene, 4-methylstyrene, 3-methylstyrene, 4-methoxystyrene, 2-hydroxymethylstyrene, 4-ethylstyrene, 4-ethoxystyrene, 3,4-dimethylstyrene, 2-chlorostyrene, 3-chlorostyrene, 4-chloro-3-methylstyrene, 3-tert-butylstyrene, 2,4-dichlorostyrene, 2,6-dichlorostyrene and 1-vinylnaphthalene; an unsaturated nitrile such as acrylonitrile or methacrylonitrile, an N-substituted maleimide such as N-ethylmaleimide, N-isopropylmaleimide, N-n-butylmaleimide, N-isobutylmaleimide, N-tert-butylmaleimide, N-n-octylmaleimide, N-cyclohexylmaleimide, N-benzylmaleimide and N-phenylmaleimide, an unsaturated dicarboxylic acid anhydride such as maleic anhydride, itaconic anhydride, citraconic anhydride or tetrahydrophthalic anhydride, acrylic or methacrylic acid, a polyol acrylate or methacrylate such as the diacrylates and dimethacrylates of ethylene glycol, propylene glycol, 1,3-butanediol, 1,4-butanediol, 1,6-hexanediol, neopentylglycol, 1,4-cyclohexanediol, 1,4-cyclohexanedimethanol, 2,2,4-trimethyl-1,3-pentanediol, 2-ethyl-2-methyl-1,3-propanediol, 2,2-diethyl-1,3-propanediol, diethylene glycol, dipropylene glycol, triethylene glycol, tripropylene glycol, tetraethylene glycol, tetrapropylene glycol, trimethylolethane, trimethylolpropane, glycerol, pentaerythritol, the triacrylates and trimethacrylates of trimethylolethane, trimethylolpropane, glycerol and pentaerythritol, pentaerythritol tetraacrylates and tetramethacrylates, dipentaerythritol di(meth)acrylates to hexa(meth)acrylates, poly(meth)acrylates of mono- or polyethoxylated or mono- or polypropoxylated polyols such as triethoxylated trimethylolpropane and tripropoxylated trimethylolpropane triacrylate and trimethacrylate; tripropoxylated glycerol triacrylate and trimethacrylate; and tetraethoxylated pentaerythritol triacrylate, trimethacrylate, tetraacrylate and tetramethacrylate, an epoxidised acrylate or methacrylate chosen from 2-epoxyethylbicyclo[2.2.1]hept-5(6)-yl (meth)acrylate, epoxydicyclopentyloxyethyl acrylate, and those of formula: ##STR9## in which R.sub.1 is chosen from the hydrogen atom and the methyl radical, and n is an integer ranging from 1 to 16,

Such compounds can be prepared by reaction of an acrylic or methacrylic compound of formula: ##STR17## in which R.sup.1, A and Y have the same meanings as in the formula (I), with a pentavalent phosphorus compound, it being possible for the latter to be, for example, a compound of formula PXT.sub.3 in which X has the same meaning as in formula (II) and T denotes a halogen atom, or else a phosphorus compound of formula: ##STR18## in which R and X have the same meanings as in formula (I) and T denotes a halogen atom or else the pentasulphide P.sub.2 S.sub.5, and generally any ethylenically unsaturated monomers capable of being copolymerised by a radical process under the effect of a free-radical generator such as microwaves, beta, gamma or ultraviolet radiation or a chemical initiator such as persulphate, peroxide, hydroperoxide or diazo compound.

In the case of copolymers, the polymerisation conditions will be chosen to be as close as possible to those usually employed for the polymerisation of the ethylenically unsaturated monomer, namely, for example:

a temperature of 140.degree. C. to 300.degree. C. and a pressure approximately from 1000 to 3000 bars when this comonomer is ethylene, temperature approximately from 30.degree. C. to 90.degree. C. when this comonomer is an acrylic or methacrylic compound, a temperature approximately from 80.degree. C. to 200.degree. C. when this comonomer is a vinylaromatic hydrocarbon.
