A vinyl chloride resin composition extremely excellent in weather resistance and impact resistance, which comprises 2 to 30 parts by weight of (A) a graft copolymer obtained by polymerizing 5 to 30 parts by weight of (a−2) a graft monomer component comprising 92 to 100 wt% of methyl methacrylate and 0 to 8 wt% of one or more monomers selected from among alkyl methacrylates wherein the alkyl group has 2 to 8 carbon atoms, alkyl acrylates wherein the alkyl group has 1 to 8 carbon atoms, unsaturated nitriles, and aromatic vinyls in the presence of 70 to 95 wt% of (a−1) a crosslinked acrylic rubber polymer comprising 81 to 95 wt% of butyl acrylate, 4 to 18 wt% of an alkyl acrylate wherein the alkyl group has 8 to 12 carbon atoms, and 0.2 to 0.8 wt% of a polyfunctional monomer (with the proviso that the total amount of the polymer (a−1) and the monomer component (a−2) is 100 parts by weight) and 100 parts by weight of (B) a vinyl chloride resin.
