Polypropylene impact blends having improved optical properties |
摘要 |
A polypropylene impact blend having a good overall balance of mechanical properties, particularly high impact strength, and surprisingly high clarity is disclosed which includes about 70 to about 90% by weight of a polypropylene, about 1 to about 18% by weight of a low density polyethylene and about 2 to about 24% by weight of an amorphous ethylene-propylene copolymer elastomer, with or without a non-conjugated diene, having a high combined ethylene content. The polypropylene impact blends are useful for making molded or extruded shaped articles and the like which are essentially clear.
