Abstract

An EPDM elastomer (e.g. ethylene/propylene/ethylidene norbornene) is blended with polypropylene (70-98 wt. %) and a halogenated phenol resin (1-20 parts per 100 parts of the elastomer). The blend may be cured and molded to provide articles having high flexural modulus and high impact resistance at low temperatures.
