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