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) an organic over-based complex of Group I or II-a metal bases, for example, barium phenate or sulfonate, an over-based calcium phenate or sulfonate or the like. 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.
