Edward H. Price 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).

  • Ion-exchange structures of copolymer blends
    Patent number: 4255240
    Abstract: Ion-exchange films, membranes and laminar structures incorporating a layer of a blend of a first fluorinated polymer which contains sulfonyl groups in ionizable form and a second fluorinated polymer which contains carboxylic acid functional groups, when used to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency and low power consumption. They can be made by synthesis of precursor polymers in melt-fabricable form, blending, fabrication of the film, membrane or laminar structure, and hydrolysis of the functional groups to ionizable form, such as the free acid form or alkali metal salt thereof.
    Type: Grant
    Filed: June 4, 1979
    Date of Patent: March 10, 1981
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Charles J. Molnar, Edward H. Price, Paul R. Resnick
