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 , NiO, Ni 2 Si, NiS, and nickel stearate, and (B) at least one vanadium compound selected from the group consisting of NH 4 VO 3 , Mg(VO 3 ) 2 , NaVO 3 , VOSO 4 , V 2 O 4 , V 2 O 5 and vanadium oxyacetylacetonate. 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. Hydrates of the additive compounds may also be used.
