ABSTRACT:
Compositions which are effective in stabilizing polymers against the deteriorative effects of heat are provided comprising (1) an organic tin compound or mixture of organic tin compounds, (2) an organic compound having an aromatic ring which is substituted with a hydroxyl (--OH) group and a mercapto (--SH) group ortho to each other, and, optionally, (3) an organotin mercaptide or mixture of organotin mercaptides. Also provided are polymer compositions containing said stabilizers and articles of manufacture made from said stabilized polymer compositions.
