ABSTRACT OF THE DISCLOSURE Smoke retardant vinyl chloride and vinylidene chloride polymer compositions are obtained by including there- in a synergistic mixture of (A) at least one nickel compound selected from the group consisting of NiCO3, NiCl2, NiO, NiS and nickel acetylacetonate and (B) at least one zinc compound selected from the group consisting of ZnCO3,ZnCrO4, ZnMoO4, Zn3(PO4)2, Zn2SiO4, ZnSO4, ZnTiO3, Zn2ZrO4, zinc ammonium sulfate, zinc borate, zinc acetylacetonate, zinc formate, zinc oxalate, and M2-2xZn3+x[Fe(CN)6]2?yH2O wherein M is an alkali metal, x is from o to 1, and y is from o to 4. Substantial smoke retardation is also obtained by including the above nickel compounds or zinc compounds individually in the vinyl chloride or vinylidene chloride polymer compositions. These compositions are useful whenever smoke resistance is desirable, such as in carpets, house siding, plastic com- ponent for airplane interiors and the like.
