Abstract
An acrylonitrile resin composition capable of affording shaped articles having superior alcohol resistance, impact strength, transparency and gas-impermeability, said composition consisting essentially of (A) a resinous copolymer obtained by polymerizing a monomeric mixture consisting of (1) 60 to 90% by weight of acrylonitrile, (2) 1 to 35% by weight of at least one acrylic monomer selected from the group consisting of alkyl acrylates and alkyl methacrylates with the alkyl group containing 1 to 6 carbon atoms, and (3) 0.5 to 15% by weight of an alkyl methacrylate with the alkyl group containing 12 to 18 carbon atoms; and (B) a graft copolymer obtained by polymerizing (1) 40 to 80 parts by weight of a monomeric mixture consisting of (i) 30 to 90% by weight of acrylonitrile, (ii) 1 to 70% by weight of at least one acrylic monomer selected from the group consisting of alkyl acrylates and acryl methacrylates with the alkyl group containing 1 to 6 carbon atoms and (iii) 0 to 15% by weight of an alkyl methacrylate with the alkyl group containing 12 to 18 carbon atoms, in the presence of (2) 20 to 60 parts by weight of a diene-type rubbery polymer composed of at least 50% by weight of a …
