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 P-hydrocarbonphosphonate having at least one to thirty carbon atoms in the hydrocarbon group. Vinyl chloride polymer compositions stabilized with the above disclosed stabilizer composition are also disclosed.
