THERMOPLASTIC POLYMER BLENDS OF EP OR EPDM POLYMER WITH CRYSTALLINE POLYPROPYLENE

摘要

THERMOPLASTIC POLYMER BLENDS OF EP OREPDM POLYMER WITH CRYSTALLINE POLYPROPYLENEABSTRACT OF THE DISCLOSUREEP or EPDM polymers having a high ethylene contentand a high ratio of ethylene units in runs of three or moreto isolated ethylene units in the polymer are physicallyblended with crystalline polypropylene. The blends exhibitgood tensile strength and modulus, and are useful to preparemolded products, tubing, liners, and like products.- 1 -
