Abstract
The invention comprises monoacrylate (inccluding methyl-substituted-acrylate) esters of chain terminated monohydric polyoxyalkylene glycols having at least four alkylene oxide units, said ester containing only one unsaturated group per molecule and also their polymers and their copolymers with olefinic monomers. The monomeric esters have the general formula: <FORM:0848919/IV(a)/1> where R, R1 and R11 are hydrogen or methyl, A is a divalent alkylene group, n is at least 4 and T is a terminal group inert during esterification such at alkoxy, phenoxy, acyloxy, cyano, halogen, halomethylenoxy (-OCH2Hal), -OCHHal2 or -OCHal3. Preferred esters have at least three consecutively-connected carbon atoms between successive ether oxygen atoms. The monomeric esters function as internal plasticisers when copolymerised. Specified comonomers include vinyl and vinylidene chlorides, vinylidene cyanide, acrylic acids, esters, amides and nitriles, olefinic hydrocarbons, maleic anhydride and esters, fumaric acid and esters and polyallyl sucrose. Proportions of from 5 to 99% by weight of the esters are mentioned. Polymerisation may be effected in bulk, solution, aqueous suspension or aqueous emulsion. Per-type catalysts may be used.ALSO:The invention comprises monoacrylate (including methyl-substituted-acrylate) esters of chain terminated monohydric polyoxyalkylene glycols having at least four alkylene oxide units, said ester containing only one unsaturated group per molecule. The esters have the general formula: <FORM:0848919/IV(b)/1> where R, R1 and R11, are hydrogen or methyl, A is a divalent alkylene group, n is at least 4 and T is a terminal group inert during esterification such as alkoxy, phenoxy, acyloxy, cyano, halogen, halomethylenoxy (-OCH2Hal), - OCHHal2 or -OCHal3. They may be prepared by esterifying a chain-terminated polyoxyalkylene glycol (from an alkylene oxide and a chain terminator containing a reactive hydrogen atom) with an acrylic acid, acid chloride or anhydride or by reacting the acrylic acid or acid chloride with an alkylene oxide and subsequently treating the resulting ester with another (saturated) acid to react with the remaining hydroxy group. Preferred esters are obtained by condensing an alkylene monoxide such as tetrahydrofuran with an acrylic acid halide in the presence of a FriedelCraft's catalyst, the halogen atom forming the chain-terminating group (T). Preferred esters have at least three consecutively-connected carbon atoms between successive ether oxygen atoms.
