| abstract | 1,175,546. Rubbery acrylate copolymers. POLYMER CORP. Ltd. 16 Jan., 1967 [17 Jan., 1966], No. 2285/67. Heading C3P. Rubbery acrylate copolymers comprise the polymerization product of (a) 70-99 parts by weight of a monomer selected from (1) C 5- C 11 alkyl acrylates, and (2) mixtures of such acrylates with C 5 -C 11 alkoxyalkyl or alkylthioalkyl acrylates, in which the alkyl acrylate forms 50-90% by weight of the mixture, (b) 0À1-10 parts by weight of a monomer which is the reaction product of a saturated α-haloaliphatic monocarboxylic acid with an epoxide of the formula where one of Q and Q<SP>1</SP> is a monoolefinically unsaturated hydrocarbon radical and the other is H or a saturated hydrocarbon radical, said radicals having 1-7 carbon atoms and optionally each containing oxygen in the form of an ester or ether linkage and, where both Q and Q<SP>1</SP> are hydrocarbon radicals, they may be linked together to form a cycloaliphatic radical, and optionally (c) one or more other copolymerizable monomers which are not monoolefinically unsaturated monoepoxides. Monomer component (b) may be, for example, the reaction product of chloroacetic acid and glycidyl acrylate or methacrylate, chloroacetic acid and allyl glycidyl ether, bromoacetic acid and glycidyl methacrylate, or of chloroacetic acid and vinylcyclohexene monoxide. Optional monomer component (c) may be, for example, acrylonitrile or divinylbenzene. The copolymers can be prepared by polymerizing the appropriate monomers in solution, in bulk or, preferably, in aqueous emulsion in the presence of an initiator and, optionally, a modifier. Suitable emulsifiers include soaps, aliphatic sulphates, aryl or alkaryl sulphonates, and salts of amines. Suitable initiators include benzoyl peroxide, persulphates, sodium perborate, hydrogen peroxide, cumene hydroperoxide, diazoaminobenzene, and redox systems. Aliphatic mercaptans may be used as a polymerization modifier. The rubbery copolymers can be vulcanized using an alkali metal or ammonium salt of a weak inorganic or organic acid as curing agent, e.g. sodium carbonate, ammonium acetate, ammonium benzoate, sodium oleate and potassium stearate. In examples, the copolymers are compounded and vulcanized with a composition comprising carbon black, stearic acid, phenyl-#-naphthylamine, sodium stearate, potassium stearate and sulphur. |
