Stabilizer compositions for PVC

摘要

Compositions which are effective in stabilizing polymers against the deteriorative effects of heat are provided comprising (1) an organic antimony compound or mixture of organic antimony compounds, (2) a mercaptan-containing organic compound or mixture of mercaptan-containing organic compounds, and (3) a metal mercaptoalcohol or mixture of metal mercaptoalcohols. Also provided are polymer compositions containing said stabilizers, a process for stabilizing polymers, and articles of manufacture made from stabilized polymer compositions.
