Abstract
Thermoplastic resin composition having excellent transparency, impact strength, weatherability and gas screening effect comprising a graft copolymer which is produced by polymerizing a vinyl cyanide monomer and an unsaturated carboxylic acid ester monomer in the presence of a gummy copolymer produced by polymerizing a conjugated diolefinic monomer (0 to 90 parts by weight), at least one vinyl cyanide monomer (5 to 60 parts by weight) and at least one unsaturated carboxylic acid ester monomer (5 to 90 parts by weight), in admixture with or without a resin copolymer of a vinyl cyanide monomer and an unsaturated carboxylic acid ester monomer.
