Abstract
The invention provides novel blends and processes for producing such blends which include a polyamide, an olefinic acid copolymer or salt thereof, and a maleated ethylene/propylene rubber, wherein such novel blends may be processed by conventional extrusion and molding techniques, do not require a separate curing step or procedure in the overall production process, and which produces articles which have some physical characteristics similar to those exhibited by thermoplastic elastomers. The inventive compositions exhibit feature excellent resistance to zinc chloride solutions and are formable in a single melt blending step.
