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 NiCO 3 , NiCrO 4 , NiI 2 , NiO, NiS, NiSO 4 , nickel acetylacetonate, nickel citrate and nickel formate and (B) at least one iron compound selected from the group consisting of Fe 3 C, Fe 2 (MoO 4 ) 3 , Fe 2 O 3 , Fe 3 O 4 , FeS, cyclopentadienyl iron dicarbonyl, ferric acetylacetonate, ferric hydroxy distearate, and ferrocene. Substantial smoke retardation is also obtained by including the above nickel compounds or iron compounds individually in the vinyl chloride or vinylidene chloride polymer compositions.
