SMOKE SUPPRESSANT VINYL CHLORIDE AND VINYL IODINE CHLORIDE POLYMER COMPOSITIONS

摘要

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, Cu2O, CuO, CuSCN, CuSO4, 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.
