ABSTRACT:
Smoke retardant vinyl chloride and vinylidene chloride polymer compositions are obtained by including therein a synergistic mixture of (A) at least one nickel compound selected from the group consisting of NiCO.sub.3, NiCrO.sub.4, NiMoO.sub.4, NiO, NiSO.sub.4, NiSnO.sub.3 and nickel stearate and (B) at least one copper compound selected from the group consisting of CuI, CuO, CuSCN, and 2-aminothiophenol Cu(I). Substantial smoke retardation is also obtained by including the above nickel compounds or copper compounds individually in the vinyl chloride or vinylidene chloride polymer compositions.
