Abstract
Molded articles of silane-crosslinked blends comprising a polyolefin elastomer and a crystalline polyolefin polymer exhibit desirable tensile strength and/or compression set properties, and are prepared by (i) blending a low density polyolefin elastomer with a crystalline polyolefin polymer, (ii) grafting the blend with a silane crosslinker, (iii) shaping the silane-grafted blend into the molded article, and (iv) curing the shaped, silane-grafted blend with water, preferably in the presence of a cure catalyst.
