Disclosed is a polyvinyl chloride resin composition containing, per 100 parts by weight of a polyvinyl chloride resin, 0.005-5 parts by weight of a vinyl alcohol polymer having a carboxyl group, a sulfonic acid group, or a salt of a carboxyl group or sulfonic acid group at an end, while having a saponification degree of 30-99.9 mol% and a viscosity average polymerization degree of not more than 1000, and 0.01-5 parts by weight of a zinc compound. Also disclosed is a polyvinyl chloride resin composition containing, per 100 parts by weight of a polyvinyl chloride resin, 0.005-5 parts by weight of a vinyl alcohol polymer having an alkyl group containing 6 or more carbon atoms at an end, while having a saponification degree of 30-99.9 mol% and a viscosity average polymerization degree of not more than 1000, and 0.01-5 parts by weight of a zinc compound. The polyvinyl chloride resin compositions have excellent thermal stability during molding, and can provide a molded product which rarely suffers from coloration. |
