ABSTRACT:
An impact polypropylene blend having an excellent balance of overall mechanical properties, particularly high impact strength, and significantly improved optical properties, comprising about 2 to about 22% by weight of an ethylene-propylene copolymer elastomer and about 1 to about 15% by weight of a low density polyethylene which are at least partially cured in the presence of polypropylene. The high impact polypropylene blends containing about 70 to about 95% by weight polypropylene have surprisingly good optical properties and are useful for making molded or extruded high clarity articles, such as containers, films, and the like.
