More Information
Summary:The present invention provides a vinyl chloride-based resin composition which is highly excellent in weatherability, impact resistance and gloss is provided, which comprises:(A) 100 parts by weight of a vinyl chloride-based resin;(B) from 1 to 30 parts by weight of a graft copolymer which is obtained by graft-polymerizing;(C) from 0.1 to 5 parts by weight of a methyl methacrylate-based two stages polymer which is obtained by, in the presence of a polymer while a solution of 0.1 g of said polymer in 100 ml of chloroform showing a specific viscosity (etasp) of 0.7 or more at 30° C., comprising from 0 to 50% by weight of a repeating unit derived from methyl methacrylate, while a solution of 0.1 g of said two stages polymer in 100 ml of chloroform showing a specific viscosity of 0.5 or more at 30° C.; and(D) from 1 to 20 parts by weight of calcium carbonate.
