Abstract

This invention relates to blends of sulfonated elastomers with crystalline polyolefins. The sulfonated elastomer comprises from about 0.2 to about 20 mole percent sulfonate groups, at least 95% of which are combined with metal counter ions selected from the group consisting of Groups I and II of the Periodic Table of the Elements, aluminum, and lead; organic amines; and mixtures thereof. The crystalline polyolefin is preferably selected from the group consisting of polyethylene, including high and low density polyethylenes, and polypropylene. The crystalline polyolefin comprises a minor portion of said blends.
