Abstract
PURPOSE: To provide a composition which produces a molded article wherein the surface is non-foamed skin layer and the inner part is fine foamed structure, by mixing pellets of non-foamable plasticized vinyl chloride resin compsn. with pellets of foamable vinyl chloride resin base compsn.
CONSTITUTION: A resin composition for injection molding is composed of (A) pellets consisting of non-foamable plasticized vinyl chloride resin having an average degree of polymn. of 400W900 and contg. 20W100 parts by weight of plasticizer and (B) pellets consisting of foamable plasticized vinyl chloride resin having an average degree of polymn. of 800W2000 and contg. 20W120 parts of plasticizer, 0.2W2.0 parts of foaming agent and 2W30 parts of acrylic resin and/or ethylene- vinyl acetate copolymer in weight ratio of A to B of 1:9W5:5. The plasticizers used in A and B may be the same or different. Di-2-ethylhexyl phthalate may be used. From the viewpoint of processability azodicarbonamide is a preferred foaming agent used in B.
