BLENDS OF SULFONATED ELASTOMERS WITH CRYSTALLINE POLYOLEFINS

摘要

(U.S. 524,512) 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. The blends have diverse applications, eg. they have excellent infection molding and extrusion properties. Thus molded shoe soles, automobile parts and extruded articles such as garden hoses may be prepared.
