ABSTRACT:
Long chain aliphatic alcohol (C.sub.16 +) is added to thermoplastic elastomer based on blend of olefin copolymer rubber (EPM or EPDM) and polyolefin resin (especially polypropylene). The blend may be uncured or dynamically partially cured. The long chain aliphatic alcohol permits injection molded articles to be demolded within a shorter time without tearing or distortion, and decreases the surface tackiness of the article.
