  • MICROPOROUS POLYOLEFIN AND METHOD OF PRODUCING THE SAME
    Publication number: 20120168976
    Abstract: A microporous film comprises a first component comprising a super high molecular weight polyolefin resin, wherein the weight-average molecular weight of the super high molecular weight polyolefin is about 1×106 to about 6×106. The microporous film also comprises a second component comprising a polyolefin resin, wherein the weight-average molecular weight of the polyolefin resin is less than about 5×105. A method of producing a microporous film comprises melting a first polyolefin resin which is a super high molecular weight polyolefin resin in a solvent to form a first mixture, and adding to the first mixture a second polyolefin resin having a weight-average molecular weight of the less than about 5×105 to form a second mixture.
