Thermoplastic polymer blends of EP or EPDM polymer with crystalline polypropylene

摘要

EP or EPDM polymers having a high ethylene content and a high ratio of ethylene units in runs of three or more to isolated ethylene units in the polymer are physically blended with crystalline polypropylene. The blends exhibit good tensile strength and modulus, and are useful to prepare molded products, tubing, liners, and like products.
