Abstract
1327095 Nitrile / (alkyl)styrene / diene copolymers STANDARD OIL CO 28 July 1970 [6 Nov 1969] 36393/70 Headings C3G and C3P Polymer compositions comprise the product obtained by copolymerizing (A) a monomer mixture of an olefinically unsaturated nitrile and styrene or an alkyl-substituted styrene in a molar ratio, maintained throughout the copolymerization, of from 5 : 1 to 80 : 1 in the presence of (B) a diene elastomer, said product containing 1-25% by weight of (B) and the molar ratio of nitrile/(alkyl)styrene polymerized and bound in the polymer product being from 1 : 1 to 5 : 1. Copolymerization is preferably effected in aqueous emulsion in the presence of a catalyst (e.g. azobisisobutyronitrile) and, optionally, a mercaptan molecular weight modifier and other additives. The nitrile monomer used is preferably acrylonitrile and the alkylstyrene monomer may be nuclear- or side chain-substituted by C 1 -C 4 alkyl groups. The diene elastomer is suitably a rubbery homopoly. mer or copolymer of butadiene, isoprene, chloroprene or piperylene; comonomers include acrylonitrile, methacrylonitrile, styrene, alphamethyl-styrene and ethyl acrylate. The desired nitrile/(alkyl)styrene ratio is maintained during copolymerization by either carrying the polymerization to low conversion or by adding further (alkyl)styrene monomer as polymerization proceeds. Polymerization can be effected batohwise, semi-continuously or continuously. The thermoplastic products obtained can be extruded or moulded into various shaped articles. or worked up in different procedures (a long list of articles and applications is disclosed). Inference has been directed by the Comptroller to Specification 1,185,306.
