An environmentally acceptable stabilizer composition is provided for enhancing the resistance to deterioration upon heating at 175.degree. C. of a vinyl chloride polymer from which lead, cadmium, mercury, thallium, and arsenic are substantially excluded, comprising (A) at least one zinc, alkali metal, or alkaline earth metal organic phosphate ester salt having per metal atom from one to a number equal to the valence of the metal of phosphate ester groups and from one to two organic groups per phosphate groups, the organic groups being alkyl, aryl, alkaryl, aralkyl, ether-interrupted allyl, or ether-interrupted aralkyl groups having from 1 to about 80 carbon atoms; and (B) at least one betadiketone compound having 5 to about 30 carbon atoms which is a cyclic or open-chain betadiketone or a zinc, alkali metal or alkaline earth metal salt thereof.
A stabilized vinyl chloride polymer composition in which the environmentally acceptable composition is used as stabilizer is also provided.
