ABSTRACT:
An improved polymer for use as an ion exchange membrane in an electrolytic cell wherein the polymer has pendant chains containing sulfonic acid ion exchange groups and has an equivalent weight of between about 800 and about 1500. The polymers have a hydration product of less than about 22,000.
The electrolytic cell and its method of operation are described when these polymers are used as ion exchange membranes.
