Abstract
Compositions comprising an organotin mercaptide, organotin sulfide or mixtures thereof; a diester of an ethylenically unsaturated dicarboxylic acid having one carboxyl group on each carbon atom of the ethenylene group; and, optionally, an organotin carboxylate are useful for stabilizing halogen-containing organic polymers against the deteriorative effects of heat, light and weathering.
