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.
