ABSTRACT:
Compositions which are effective in stabilizing polymers against the deteriorative effects of heat are provided comprising (1) a mono-organotin compound or mixture of mono-organotin compounds, (2) a mercaptan-containing organic compound or mixture of mercaptan-containing organic compounds, and, optionally (3) a diorganotin compound or mixture of diorganotin compounds. Also provided are polymer compositions containing said stabilizers and articles of manufacture made from said stabilized polymer compositions.
