Abstract

Fluorinated ion exchange polymers which have pendant side chains which contain groups wherein W is F or CF3, and R is an inonizable group, or which have such pendant side chains and also pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency. They can be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic funtional group.
