Abstract: Impact-resistant polymers having low permeability to gases and vapors are prepared by polymerizing acrylonitrile with an alphaolefin such as isobutylene, at least one member selected from the group consisting of an acrylic ester, a methacrylic ester, methacrylonitrile, an acrylamide, and a vinyl ester, and optionally another vinyl monomer component such as a vinyl aromatic monomer in an aqueous medium in the presence of a diene rubber.

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: PROCESS FOR IMPROVEMENT OF IMPACT STRENGTH IN RUBBER-MODIFIED NITRILE THERMOPLASTICS Improved impact strength of copolymers of acrylonitrile and styrene prepared in the presence of a diene rubber is achieved presoaking the diene rubber with part or the acrylonitrile and styrene monomers prior to conducting the graft polymerization reaction.

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.
