ABSTRACT:
Novel organic ion-exchange polymers and membranes formed from these polymers provide improved performance in electrolytic cells. The membranes exhibit an expanded micro-structure as the result of the removal of organic groups previously reacted with the ion-exchange groups of the polymer. The polymers are also useful in finely divided form as catalysts or deposited on a catalyst support. When formed into sheets, the polymers are useful as membranes in the separation of miscible liquids and in the separation of gases.
