<p>A graft copolymer composition obtained by mixing a graft copolymer (A) containing a rubbery polymer having a glass transition temperature of not higher than 0 DEG C as a trunk polymer and containing a alkyl ester of methacrylic acid-base polymer as a graft component, and having a mean particle size of at least 0.15 mu m, and a graft copolymer (B) having a means particle size of from 0.03 to 0.13 mu m; and a vinyl chloride-base resin composition containing the above-described graft copolymer composition as am impact modifier. The vinyl chloride-base resin composition is excellent in the impact strength and can be suitably used for the productions of pipes, window frames, joints, fences, doors, switch boxes, etc.</p> |
