Abstract
Abstract Smoke retardant vinyl chloride and vinylidene chloride polymer compositions are obtained by including therein a synergistic mixture of (A) at least one melamine molybdate or substituted melamine molybdate and (B) at least one compound selected from the group consisting of iron oxide, FeSO 4 , Fe 2 (SO 4 ) 3 , iron (III) acetylacetonate and hydrates thereof. Substantial smoke retardation is also obtained by including the above compounds individually in the vinyl chloride or vinylidene chloride polymer compositions.
