Abstract
Thermoplastic elastomer compositions of the present invention comprise a blend of from about 10 to about 48 parts by weight of a crystalline 1-olefin polymer, from about 90 to about 10 parts by weight of a styrene-butadiene rubber, and a triblock copolymer or a diblock copolymer in the amount of from about 0.1 to about 80 parts by weight or a polystyrene in the amount of from 0.1 to about 50 parts by weight. The thermoplastic elastomer blends have good physical properties, especially tensile strength, elongation at break, and tear strength. Moreover, the compositions can be repeatedly processed and yet maintain their good physical properties. The compositions, which may be partially cured, have excellent aging properties as well as paint adhesion.
