Abstract
Polymer blends of a halogen-containing polymer and a carboxyl-containing polymer are covulcanized using as the cure system (1) a metal oxy compound and (2) a quaternary ammonium salt or a monofunctional tertiary amine. The vulcanizates exhibit excellent physical properties, and are useful in fabricating hose, belting, gaskets, o-rings, and the like.
Claims22
A vulcanizable polymer blend comprising (1) from about 1 part to about 99 parts by weight of a halogen-containing polymer per 100 parts by weight of the halogen-containing and carboxyl-containing polymers, (2) from about 1 part to about 99 parts by weight of a carboxyl-containing polymer per 100 parts by weight of the halogen-containing and carboxyl-containing polymers, and (3) a cure system consisting essentially of (A) from about 0.5 part to about 20 parts by weight of a metal oxy compound selected from the group consisting of (a) a metal salt of an organic acid and (b) a non-alkali metal oxide, hydroxide, or carbonate, and (B) from about 0.1 part to about 10 parts by weight of either a quaternary ammonium salt or a monofunctional tertiary amine, said parts by weight of the cure system based on 100 parts by weight of the halogen-containing and carboxyl-containing polymers.
