Abstract
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 NiI 2 , NiMoO 4 , NiO and nickel dimethylglyoxime and (B) at least one aluminum compound selected from the group consisting of Al 2 (MoO 4 ) 3 , α-Al 2 O 3 , Al 2 (WO 4 ) 3 , ammonium-6-molybdoaluminate (III), and aluminum salicylate. Substantial smoke retardation is also obtained by including the above nickel compounds or aluminum compounds individually or aluminum ammonium sulfate, aluminum potassium sulfate, or aluminum acetylacetonate in the vinyl chloride or vinylidene chloride polymer compositions.
