摘要：
A powdery polyvinyl chloride resin composition which comprises polyvinyl chloride resin, 0.1 to 10 parts by weight of stabilizer mixture represented by the formula:
(RCOO)₂Me
wherein R is selected from alkyl groups having 5 to 8 carbon atoms and Me represents a mixture of barium and zinc, the barium and zinc metallic weight ratio being 1:5 to 5:1, and 0.1 to 10 parts by weight of a perchlorate ion type hydrotalcite compound per 100 parts by weight of the polyvinyl chloride resin. The composition has reduced tendency to mold staining and has resistance to amine staining.
