  • Ion exchange membranes
    Patent number: 4324636
    Abstract: An improved process for modifying the properties of membranes, particularly ion exchange membranes, and novel membranes characterized by a unique combination of low gas permeability and low electrical resistivity. The process comprises the steps of modifying the morphology of a pre-membrane by subjecting it to a chemical reaction, advantageously with a reactive macromolecular solute in an organic solvent.
    Type: Grant
    Filed: August 3, 1979
    Date of Patent: April 13, 1982
    Inventor: Joseph P. Dankese
