Abstract
Proposed is a polyvinyl chloride-based resin composition exhibiting excellent moldability with high flowability in molding and capable of giving molded articles having excellent mechanical properties including tensile strength and impact strength as well as heat resistance along with high resistance against yellowing by weathering. The resin composition comprises (a) a homopolymeric polyvinyl chloride resin having an average degree of polymerization of 700 to 2500, (b) an acrylic rubber-based graft copolymer, (c) an ethylene-vinyl acetate copolymeric resin of a specific copolymerization ratio and (d) an acrylonitrile-styrene copolymeric resin of a specific copolymerization ratio each in a specified weight proportion.
