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 translation: 通过将丙烯腈与α-烯烃（例如异丁烯），至少一种选自丙烯酸酯，甲基丙烯酸酯，甲基丙烯腈，丙烯酰胺和丙烯酸酯的组分聚合而制备对气体和蒸气具有低渗透性的耐冲击聚合物 乙烯基酯和任选另外的乙烯基单体组分如乙烯基芳族单体在水性介质中在二烯橡胶的存在下进行。
