  • High performance thermoplastic elastomer composition
    Patent number: 8394892
    Abstract: The present invention provides a thermoplastic elastomer composition comprising: 100 parts by weight of component (A), 10 to 100 parts by weight of component (B), 50 to 200 parts by weight of component (C), and 5 to 30 parts by weight of component (D). Component (A) is a propylene polymer having a melting point of 155° C. or more. Component (B) is a crystalline propylene-ethylene copolymer. Component (C) is an ethylene-?-olefin rubber having Mooney Viscosity of 30 to 100(ML1+4, 125° C.). Component (D) is a hydrogenated product of block copolymer comprising blocks of aromatic vinyl compound units and blocks of conjugated diene compound units.

  • REACTOR THERMOPLASTIC POLYOLEFIN ELASTOMER COMPOSITION
    Publication number: 20110218283
    Abstract: A thermoplastic elastomer composition is disclosed comprising about 100 parts by weight of component (A) and about 20 to about 100 parts by weight of component (B). Component (A) is a polypropylene resin comprising about 60 to about 90% by weight of component (i) and about 40 to about 10% by weight of component (ii). Component (i) is a propylene homopolymer or copolymer of propylene and at least one monomer group consisting of ethylene and an ?-olefin having 4 or more carbon atoms. Component (ii) is an ethylene-?-olefin copolymer comprising about 20 to about 50% by weight ethylene units. Component (B) is an ethylene-?-olefin elastomer comprising about 60 to about 85% by weight ethylene units and about 40 to about 15% by weight of ?-olefin units. Component (B) has a Mooney stress relaxation area of from 180 to 300.
