Abstract
A stabilizer composition is disclosed that enhances the resistance to deterioration upon heating of vinyl chloride polymers. The stabilizer composition comprises (A) a metal salt of a sulfur-and nitrogen- free monocarboxylic acid or a phenol and (b) a metal salt of a phosphorous acid mono-ester in which the molar ratio of phosphorous acid mono-ester to metal is 1:1. Vinyl chloride polymer compositions stabilized with the above disclosed stabilizer composition are also disclosed.
