PROBLEM TO BE SOLVED: To obtain a composition which does not cause the deposition of solids on e.g. the tip of a mold, has excellent long-term moldability and can give moldings excellent in surface smoothness by mixing a vinyl chloride resin with fly ash, an acrylic processing aid and a paraffinic lubricant in a specified ratio. SOLUTION: The vinyl chloride resin (A) used is exemplified by a vinyl chloride homopolymer or a copolymer of a vinyl chloride monomer with a copolymerizable unsaturated monomer and desirably has an average degree of 500-2,000. The fly ash (B) used is desirably one having a mean particle diameter of 0.1-30μm. The acrylic processing aid (C) used is exemplified by an alkyl methacrylate homopolymer or copolymer. The paraffinic lubricant (D) used is exemplified by Chinese wax. The mixing ratio among components A to D is 100/(0.1-500/(0.1-10)/(0.02-10). |
