John E. Theberge has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polyolefin lubricant systems and polymer composites containing such lubricants
    Patent number: 5216079
    Abstract: Lubricant systems are provided in which a polyolefin or polyolefin/polytetrafluoroethylene blend functions as a lubricant in a polymer matrix material. The resulting polymer composites containing about 1 to 30 weight percent of the novel lubricant or lubricant blend have greatly improved friction and wear properties, including lower coefficients of friction and increased surface wear resistence. The polyolefin does not remain as discrete, identifiable particles after mixing with the polymer matrix, and has an average molecular weight of less than 500,000.
    Type: Grant
    Filed: February 23, 1990
    Date of Patent: June 1, 1993
    Assignee: Kawasaki LNP Inc.
    Inventors: Jane M. Crosby, John E. Theberge
