Patents by Inventor PAUL J. BISSETT

PAUL J. BISSETT 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).

  • Lignin/polyacrylonitrile-containing dopes, fibers, and methods of making same
    Patent number: 9133568
    Abstract: The invention relates to a process for preparing a composition comprising 10 to 45% of the total solids weight lignin, polyacrylonitrile or a polyacrylonitrile copolymer, and a solvent to form a lignin-based polyacrylonitrile-containing dope and the resulting products. The dope can be processed to produce fibers, including precursor, oxidized and carbonized fibers. The oxidized fibers are of value for their flame resistant properties and carbonized fibers are suitable for use in applications requiring high strength fibers, or to be used to form composite materials.
    Type: Grant
    Filed: June 20, 2014
    Date of Patent: September 15, 2015
    Assignee: Weyerhaeuser NR Company
    Inventors: Paul J. Bissett, Carole W. Herriott
