Abstract

Thermoplastic elastomer blends of 1-olefin polymers and copolymers such as polypropylene with styrene- butadiene rubber have good physical properties such as a low brittle point, good low temperature impact resistance, minimum creep at high temperatures and good elongation. The blends can be repeatedly processed and yet maintain their good physical properties. The amount of the 1-olefin polymer or copolymer based upon the weight of the blend ranges from 15 percent to 48 percent with the amount of the styrene-butadiene rubber correspondingly ranging from 85 percent to 52 percent. The blend is mixed at a temperature at or above the melting point of the 1-olefin polymer or copolymer with two phases produced which are generally continuous. The blends which may be partially cured have excellent and unexpected ozone resistance and aging properties, as well as excellent paint adhesion.
