VINYL CHLORIDE RESIN COMPOSITION

A vinyl chloride resin composition having excellent weatherability and impact resistance is provided. The vinyl chloride resin composition comprises (A) 2 to 30 parts by weight of a graft copolymer and (B) 100 parts by weight of a vinyl chloride resin, wherein the graft copolymer (A) is obtained by polymerizing, in the presence of 70 to 95 parts by weight of a crosslinked acrylic rubber polymer (a-1) comprising 81 to 95 % by weight of butyl acrylate, 4 to 18 % by weight of an alkyl acrylate having a C8-12 alkyl group and 0.2 to 0.8 % by weight of a multi-functional monomer, 5 to 30 parts by weight of a monomer component for graft polymerization (a-2) comprising 92 to 100 % by weight of methyl methacrylate, and 0 to 8 % by weight of an alkyl methacrylate having a C2-8 alkyl group, an alkyl acrylate having a C1-8 alkyl group, an unsaturated nitrile compound or an aromatic vinyl compound, wherein the total amount of the crosslinked acrylic rubber polymer (a-1) and the monomer component for graft polymerization (a-2) is 100 parts by weight.
