Abstract
Slush moldable polyolefin powders are prepared by blending a crosslinkable silane-grafted, olefinic interpolymer, optionally containing a crystalline polypropylene homopolymer or interpolymer; and a crosslinked silane-grafted, olefinic interpolymer containing a cure catalyst, the blend optionally containing a crystalline polyolefin powder. The resulting compositions can be slush molded to make a variety of articles of manufacture, especially automotive interior components, having good hot tear properties, low hardness and no glossing after heat aging.
