摘要:
The present invention relates to polypropylene copolymer alloys which are especially suited for soft fiber and fabric applications. 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 fiber and fabric articles made from such alloys.

摘要:
Films disclosed herein contain a base or core layer comprising a first polypropylene, a second polypropylene, and a hydrocarbon resin. The base layers may also include other additives as described below. The first polypropylene is preferably a high crystallinity polypropylene having a melting point above about 155° C. or a polypropylene having a polydispersity (Mw/Mn) greater than about 4.0. The second polypropylene may be any conventional polypropylene, preferably having a melting point below about 160° C. and/or a polydispersity less than about 5.0.
