  • Oriented polymeric microporous films
    Patent number: 5317035
    Abstract: Polyolefin resin compositions and oriented microporous films prepared from same comprising an ethylene-propylene block copolymer having an ethylene content of about 10 to about 50 wt %, a propylene homopolymer or random propylene copolymer having up to about 10 wt % of a comonomer of ethylene or an .alpha.-olefin of 4 to 8 carbon atoms, a low molecular weight polypropylene, a beta-spherulite nucleating agent and an inorganic filler. The microporous films have improved breathability, strength, toughness and break elongation.
