THERMOPLASTIC POLYMER BLENDS COMPRISING EP OR EPDM POLYMERS AND HIGHLY CRYSTALLINE POLYALLOMERS

摘要

ABSTRACT OF THE DISCLOSURECertain thermoplastic blends have substan-tially improved hot strength (i.e., cohesive strengthand resistance to sagging or tearing during milling orother hot processing). The blends comprise (1) atleast one ethylene-propylene (EP) or ethylene-propy-lene-diene (EPDM) polymer and (2) at least one highlycrystalline polyallomer, and are useful for tubing,wire and cable insulation, molded items and the like.
