ABSTRACT:
In accordance with this invention there are provided organic antimony stabilizer compositions effective in stabilizing halogen containing organic polymers against the deteriorative effects of heat comprising (1) at least one organic antimony compound having at least one antimony to sulfur to carbon (i.e. Sb-S-C) linkage, (2) elemental sulfur, and (3) at least one 2-mercaptocarboxylic acid. Said 2-mercaptocarboxylic acid and elemental sulfur also serve to provide hydrolytic and UV light stability to the antimony compound per se. Also provided are stabilized organic polymer compositions comprising a halogen containing polymer and said organic antimony stabilizer composition.
