ABSTRACT:
Impact-resistant polymers having low permeability to gases and vapors and excellent thermal color stability are prepared by polymerizing an olefinic nitrile, such as acrylonitrile, optionally with an olefinic ester, such as methyl acrylate, in an aqueous medium in the presence of an elastomer which is a copolymer of an ester of an olefinically unsaturated monocarboxylic acid, such as ethyl acrylate.
