PURPOSE:To obtain a vinyl chloride resin compsn. having excellent heat stability during molding and free from initial discoloration by compounding a metal salt of an org. acid, a partially saponified satd. carboxylic acid vinyl ester polymer, and zinc oxide with a vinyl chloride resin. CONSTITUTION:The compsn. comprises 100 pts.wt. vinyl chloride resin, a metal salt of an org. acid (pref. about 0.01-10 pts.wt.), 0.1-50 pts.wt. partially saponified satd. carboxylic acid vinyl ester polymer, and 0.1-10 pts.wt. zinc oxide. |
