Abstract

Novel compositions for stabilizing chlorinated polymers, copolymers and homopolymers comprising dawsonite, an organotin .beta.-diketonate, an organic zinc compound, and an organic calcium, magnesium, barium or lanthanide compound are disclosed. The compositions of the present invention enable the content of epoxidized oils to be decreased in chlorinated polymers while preserving thermal stability.
