<p>A blend having the properties of a thermoplastic elastomer, including low permanent set, is provided by blending (A) a monoolefin copolymer rubber (e.g., 80 parts of EPM or EPDM) having high zero shear viscosity, with (B) a polyolefin resin (e.g., 20 parts of polypropylene). The blend is useful for making molded or extruded articles (e.g., gaskets, hose) which have good physical properties without requiring vulcanization.</p> |
