    摘要: Thermoplastic elastomer blends of alpha-olefin polymers and copolymers, such as polypropylene, polyethylene, etc., having a melting point of at least 90.degree. C. with hydrogenated butadiene medium and high vinyl polymers have good physical properties such as low brittle point, good impact resistance at low temperatures, minimum creep at high temperatures, and good elongation. The blends can be repeatedly processed and still maintain good physical properties. The amount of alpha-olefin polymer or copolymer in the blend may range from about 10 percent to about 60 percent with the amount of the hydrogenated polybutadiene correspondingly ranging from about 90 percent to about 40 percent based on the combined weight of the two components. The blends are mixed at temperatures at least as high as the melting point of the alpha-olefin polymer or copolymer. These blends have excellent ozone resistance and aging properties, as well as excellent paint adhesion.
