  • Microporous materials and methods of making the same
    Patent number: 6632850
    Abstract: Microporous materials and articles are disclosed. The microporous materials contain a crystallizable propylene-containing polymer, a beta-nucleating agent, and a diluent that is miscible with the polymer at a temperature above the melting temperature of the polymer and that phase separates from the polymer at a temperature below the polymer crystallization temperature. The invention is also directed to methods of forming the microporous material using thermal induced phase separation and subsequent processing.
    Type: Grant
    Filed: April 4, 2001
    Date of Patent: October 14, 2003
    Assignee: 3M Innovative Properties Company
    Inventors: Shannon Kay Hughes, Robert Steven Kody, James Stephen Mrozinski, Myles Lee Brostrom
