摘要： A vinyl chloride resin composition which has a high impact resistance, can suitably be used in producing, for example, pipes and window frames, and comprises a graft copolymer A having an average particle size of at least 0.15 mu m and obtained by copolymerizing 50 to 90 % of a rubber latex solid having a glass transition temperature of 0 DEG C or below and obtained by polymerizing 50 to 100 % of butadiene and/or an alkyl acrylate, 0 to 40 % of an aromatic vinyl monomer, 0 to 10 % of a vinyl monomer and 0 to 5 % of a polyfunctional monomer with 10 to 50 % of a mixture of 10 to 100 % of an alkyl methacrylate, 0 to 90 % of an aromatic vinyl monomer, 0 to 25 % of a vinyl cyanide monomer and 0 to 20 % of a vinyl monomer, a graft copolymer B having an average particle size of 0.05 to 0.13 mu m and obtained by copolymerizing 50 to 90 % of the rubber latex solid with 10 to 50 % of the mixture, and a vinyl chloride resin C, wherein the weight ratio of copolymer A to copolymer B ranges from 50/50 to 95/5 and the weight ratio of the total of copolymers A and B to vinyl chloride resin C ranges from 1/99 to 30/70.
