Abstract: (5115) RUBBER-MODIFIED HIGH NITRILE COPOLYMERS WITH IMPROVED IMPACT RESISTANCE The inclusion of a small amount of an ester-type plasticizer in the rubber polymerization recipe in the production of rubber-modified high nitrile copolymer resins produces resins having markedly improved impact resistance at both low and high temperatures.

Abstract: A polymerization process is described in which impact resistant methacrylonitrile homopolymers and copolymers are prepared in the presence of a diene rubber by free radical polymerization at improved rates by conducting the polymerization in aqueous emulsion in the presence of some preformed seed polymer having small particle size.

Abstract: 1444292 Graft polymers STANDARD OIL CO 26 March 1974 [17 May 1973] 13319/74 Heading C3G A graft polymer is produced by polymerizing 100 parts by weight of (A) at least 70% by weight of an olefinically unsaturated nitrile and (B) up to 30%, by weight based on the weight of (A) plus (B), of an ester having the structure wherein R 1 is -H, C 1 to C 4 -alkyl or halogen, and R 2 is C 1 to C 6 -alkyl, allyl or an epoxy group having 2 to 6 carbon atoms in the presence of 1 to 40 parts by weight of (C) a rubbery copolymer of 5 to 25% of polymerized butadiene and/or isoprene and 95 to 75% of polymerized ester having the said structure as above. Examples are given in which acrylonitrile and methyl acrylate are grafted in aqueous emulsion on to a copolymer of butadiene, glycidyl acrylate and n-butyl acrylate or ethyl acrylate or of butadiene, allyl methacrylate and ethyl acrylate.
