    摘要: Disclosed is a polyvinyl chloride resin powder composition for rotational molding, which is prepared by dry-blending a plasticizer and a stabilizer with a polyvinyl chloride resin followed by incorporating from 0.1 to 5 parts by weight, to 100 parts by weight of the polyvinyl chloride resin, of a finely divided polyvinyl chloride resin having a viscosity average polymerization degree of from 2000 to 5000 into the resulting dry blend. Also disclosed is a method of producing a molded article by subjecting the composition to rotational molding. The composition has good powder flowability for rotational molding, and the molded article from the composition is free from pin holes and blocks on the surface thereof.
