  • Patent number: 7662896
    Abstract: Described are fluorochemical surfactants derived from nonafluorobutanesulfonyl fluoride that contain polyalkyleneoxy side chains and may be copolymerized with acrylic acid or methacrylic acid to form polyacrylates or polymethacrylates. The surfactants surprisingly lower the surface tension of water and other liquids in the same or similar low values achieved by premier surfactants such as those derived from perfluorooctane sulfonyl fluoride.
    Type: Grant
    Filed: August 1, 2008
    Date of Patent: February 16, 2010
    Assignee: 3M Innovative Properties Company
    Inventors: Patricia M. Savu, Sandra A. Etienne
