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 NiCrO.sub.4, NiMoO.sub.4, Ni.sub.2 O.sub.3, Ni.sub.3 (PO.sub.4).sub.2, nickel metal, nickel formate, and nickel oxalate and (B) at least one vanadium compound selected from the group consisting of LaVO.sub.4, Na.sub.3 VO.sub.4, VB.sub.2, VN, V.sub.2 O.sub.3 and vanadium metal. Substantial smoke retardation is also obtained by including the above nickel compounds or vanadium compounds individually in the vinyl chloride or vinylidene chloride polymer compositions, except for vanadium metal. Hydrates of the additive compounds may also be used.
