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 CuI, Cu.sub.2 O, CuO, CuSCN, CuSO.sub.4, Cu(II) 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.
Claims12
A smoke retardant composition comprising a vinyl chloride or vinylidene chloride polymer together with a smoke retardant amount of
- A. at least one melamine molybdate or substituted melamine molybdate, the melamine or substituted melamine having the formula ##STR6## wherein X is hydrogen or an alkyl, alicyclic, aralkyl, alkaryl, aryl or heterocyclic group containing from 1 to 10 atoms of C, O, S and/or N, and with two X's on each of one or more nitrogen atoms optionally being joined together to form a heterocyclic ring;
- and
- B. at least one compound selected from the group consisting of CuI, Cu.sub.2 O, CuO, CuSCN, CuSO.sub.4, Cu(II) acetylacetonate, and hydrates thereof.
