Abstract
A composition consisting essentially of 65 to 89% by weight of crystallizable polyamide, 10 to 30% by weight polyethylene, and 1 to 20% by weight of a copolymer comprising polymerized units of ethylene and at least one .alpha.,.beta.-ethylenically unsaturated carboxylic acid having from 3 to 8 carbon atoms, the copolymer having from 15 to 80% of carboxylic acid groups ionized by neutralization with metal ions of zinc, cadmium or lead. The composition possesses good tensile properties including toughness and is useful for moldings and insulated wire jacketing.
