Abstract:
1. A vinyl chloride resin composition having excellent weatherability and impact resistance which comprises: (a) 100 parts by weight of a vinyl chloride resin, (b) 1-10 parts by weight of a graft copolymer which is obtained by polymerizing 25 to 75 parts by weight of a graft monomer component to 25 to 75 parts by weight of a crosslinked elastomeric polymer so that the total thereof is 100 parts by weight, and the methyl ethyl ketone-soluble portion of which has a reduced viscosity n said graft monomer component being composed of 40 to 100% by weight of methyl methacrylate and 0 to 60% by weight of at least one monomer selected from the group consisting of an alkyl acrylate having a C said polyfunctional monomer being selected from the group consisting of an aromatic polyfunctional vinyl compound, a dimethacrylic acid ester of a polyhydric alcohol, an allyl ester of an unsaturated carboxylic acid, a diallyl compound and a triallyl compound, and said other monomers being selected from the group consisting of monomers having a single vinyl group, and (c) 10 to 30 parts by weight of calcium carbonate.
