A vinyl halide resin stabilizer composition which essentially contains: (a) an antimony organic sulfur-containing compound, for example, antimony alkyl mercaptides, antimony mercaptoacid esters and the like, and (b) an alkali or alkaline earth metal salt of an organic acid, such as Group I or Group II-a Periodic Table metal salts of carboxylic acids. These compositions synergistically contribute to the long term heat stability of vinyl halide resin compositions and offer significant heat stabilization economies. Efficiencies of the antimony organic compounds are improved in the compositions disclosed thereby permitting the reduction in amounts of such compounds needed for stabilization, and the inhibition of stabilizer exudate from the stabilized resin. |
