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 NiCrO 4 , NiO and Ni 3 (PO 4 ) 2 and (B) at least one antimony compound selected from the group consisting of antimony metal, SbCl 3 , Sb 2 S 3 , Sb 2 (SO 4 ) 3 , sodium meta-antimonate and antimony triacetate. Substantial smoke retardation is also obtained by including the above nickel compounds or antimony compounds individually in the vinyl chloride or vinylidene chloride polymer compositions.
