POLYPROPYLENE COPOLYMER ALLOY, PROCESS FOR ITS PRODUCTION AND USES OF THE ALLOY

摘要

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