Patents by Inventor Joseph C. Sentisi

Joseph C. Sentisi 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).

  • Separator membranes for electrochemical cells
    Patent number: 4230549
    Abstract: This disclosure is directed to polymer membranes to be used in electrochemical cells and improved processes for producing the same. The membranes are produced by radiation grafting techniques. The improved process includes the grafting of a hydrophilic monomer, such as methacrylic acid in a chlorinated organic solvent onto an inert base film such as polyethylene. The process also includes but is not limited to the use of inhibitors to limit homopolymerization of a grafting material, as well as emulsifying agents to lower the electrolytic resistance of the finished membrane.
    Type: Grant
    Filed: May 31, 1977
    Date of Patent: October 28, 1980
    Assignee: RAI Research Corporation
    Inventors: Vincent F. D'Agostino, Joseph Y. Lee, Joseph C. Sentisi
