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 nitrogen-free monocarboxylic acid or a phenol and (B) a hydrogen phosphite ester of an ortho-phenylethylidene-substituted phenol. Vinyl chloride polymer compositions stabilized with the above disclosed stabilizer composition are also disclosed.
