Polymer stabilising compositions, polymers stabilised therewith and shaped articles formed from such polymers.

摘要

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.
