Abstract
Abstract The present invention relates to polymer compositions containing polyphenylene sulfide, a polymeric grafting agent and an ethylene copolymer. The polymeric grafting agent is a copolymer of at least about 50% by weight ethylene, about 0.5% to about 15% by weight of a first reactive moiety selected from the group consisting of: (i) an unsaturated epoxide of 4-11 carbon atoms, (ii) an unsaturated isocyanate of 2-11 carbon atoms, (iii) an alkoxy or alkyl silane wherein the alkyl group is from 1-12 carbon atoms, and (iv) an oxazoline; and about 0 to about 49% by weight of a second moiety selected from at least one of an alkyl acrylate, alkyl methacrylate, vinyl ether, carbon monoxide, and sulfur dioxide, where the alkyl and ether groups are of 1-12 carbon atoms. The ethylene copolymer comprises about 1% to about 20% by weight of an ethylene copolymer which comprises at least about 50% by weight ethylene, about 1% to about 35% by weight of an acid-containing unsaturated mono-carboxylic acid, and about 0 to about 49% by weight of a moiety selected from at least one of alkyl acrylate, alkyl methacrylate, vinyl ether, carbon monoxide, and sulfur dioxide, and further wherein the acid groups are neutralized from 0-100% by a metal ion. The molar ratio of polymeric grafting agent to ethylene copolymer preferably ranges from about 1.0 to about 5.5.
