A resin stabilizer composition which essentially contains: (a) an organotin sulfur-containing compound, for example, organotin mercaptides, organotin mercaptoacids, organotin mercaptoacid esters, organotin sulfides, organothiostannoic acids and the like, and (b) a metal compound from one of the groups of (1) an alkali metal bisulfite, carbonate, hydroxide, oxide, thiocarbonate bicarbonate, or metabisulfite, and (2) an alkaline earth metal oxide or hydroxide. These compositions remarkably contribute to the long term heat stability of vinyl halide resins. Furthermore, among other advantages, significant economies and synergistic resin heat stabilization are offered by these stabilizer compositions.
