Homogeneous stabilizer compositions for vinyl halide polymers

Abstract From the Canadian patent

In accordance with the present invention it has been, found that liquid stabilizer compositions for vinyl halide polymers that are compatible with and form stable mixtures with epoxidized glycerides can be prepared by a process which comprises heating a non-homogeneous mixture comprising (A) at least one epoxidized glyceride, (B) at least one hydrocarbonsoluble basic alkali or alkaline earth metal salt of a monocarboxylic acid, and (C) a hydrocarbon diluent at an, elevated temperature until the mixture is homogeneous. Generally the metal salts are alkaline earth metal salts such as calcium and barium, and the basic alkaline earth metal salt utilized in this system is a salt of an aliphatic …
