  • Polyolefin resin composition and applications thereof
    Patent number: 9096746
    Abstract: There are provided a polyolefin resin composition having excellent mechanical properties and thermal resistance; a film formed of the polyolefin resin composition, which has excellent mechanical properties and thermal resistance and which is less likely to suffer from fisheyes; a microporous membrane having excellent permeability and shutdown properties in addition to the above-mentioned physical properties; and applications thereof. Such objects are accomplished by a polyolefin resin composition containing an ultra-high molecular weight ethylene polymer (A), a 4-methyl-1-pentene polymer or 3-methyl-1-pentene polymer (B), and a polymer of an olefin having 2 to 12 carbon atoms (C) at an intended ratio.
    Type: Grant
    Filed: August 29, 2012
    Date of Patent: August 4, 2015
    Assignee: MITSUI CHEMICALS, INC.
    Inventors: Nobuhisa Mikawa, Motoyasu Yasui, Akiyoshi Taguchi, Kazuto Sugiyama, Yasuhiro Kai, Kenji Sugimura
