  • Thermoplastic elastomer composition and method for preparation
    Patent number: 3957919
    Abstract: A thermoplastic elastomer formed by an EPDM interpolymer, an uncross-linked polyethylene and an uncross-linked polymer of a monoolefin containing 3 to 16 carbon atoms and preferably polypropylene and in which the polyethylene component is present in an amount of at least 4% and preferably 5-15% by weight of the combined weight of the polymeric material and which are simultaneously subjected to hot working and a free radical reaction.
