Abstract
PURPOSE: To obtain a cation exchange membrane which affords the electrolysis of salt in high current efficiency, even by extracting a concentrated NaOH from the cathode chamber, by treating a membrane of a fluorocarbon polymer with pyridine, and reacting the product with HBr-phenol solution.
CONSTITUTION: A membrane of a fluorocarbon having -O-CF2CF2SO2X (X is halogen other than F) or having the above group and a sulfonic acid group, is treated with pyridine, and then reacted with HBr-phenol solution. Carboxylic acid groups can be introduced into the membrane as a whole, or into the skin layers of both surfaces of the membrane, or into the skin layer of one surface of the membrane.
