ABSTRACT:
Compositions for stabilizing halogen-containing organic polymers against the deteriorative effects of heat, light and weathering and which are non-irritating to eyes and mucous membranes, comprise the reaction product produced by combining an organotin oxide, an ethylenically unsaturated dicarboxylic acid ester and a mercaptan, wherein the chemical equivalence of the mercaptan is less than the chemical equivalence of the diorganotin oxide and the chemical equivalence of the diorganotin oxide is less than the chemical equivalence of the ester compound.
