REACTOR THERMOPLASTIC POLYOLEFIN ELASTOMER COMPOSITION |
摘要 |
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 anα-olefin having 4 or more carbon atoms. Component (ii) is an ethylene-α-olefin copolymer comprising about 20 to about 50% by weight ethylene units. Component (B) is an ethylene-α-olefin elastomer comprising about 60 to about 85% by weight ethylene units and about 40 to about 15% by weight ofα-olefin units. Component (B) has a Mooney stress relaxation area of from 180 to 300. |
