Polymers, and novel compositions and films therefrom
Abstract:
A novel propylene copolymer is disclosed. Also disclosed is a novel composition comprising about 85 to about 99 weight percent of a polymeric ethylenic containing component having a density no greater than 0.94 g/cc, and about 1 to about 15 weight percent of a novel propylene copolymer comprising from about 60 to about 80 weight percent propylene, based on the copolymer, and from about 20 to about 40 weight percent olefin comonomer units, the propylene copolymer having a viscosity of about 1 to about 2,000 mPa·s at 190° C. and a needle penetration of greater than about 150 to about 300 dmm. Also disclosed are films produced from the composition, both blown and cast, and both monolayer and multilayer. Also disclosed are processes for stretch wrapping and forming blown film.
