发明名称 Polypropylene copolymer alloys and process for making
摘要 The present invention relates to polypropylene alloys which are especially suited for soft fiber and fabric applications. An embodiment of these alloys comprise an ethylene-propylene random copolymer having an ethylene content of from about 1.0 to 5.0% by weight, in an amount of from about 40 to 90% by weight of the alloy; and an ethylene-propylene bipolymer having an ethylene content of from about 10 to 30% by weight, in an amount of from about 10 to 60% by weight of the alloy. The present invention further relates to a hybrid process for making these alloys.
