Abstract

PURPOSE: The introduction of carboxyls into fluorocarbon polymer membranes bearing reactive groups gives cation-exchanging membranes showing high heat and chemical resistance, durability and current efficiency when used as electrolytic diaphragm.
CONSTITUTION: Carboxyls are introduced into a membrane of fluorocarbon polymer bearing reactive groups of formula IWIII on side chains by allowing an aryl compound bearing carboxyls or groups convertible into carboxyls of formula IV (X is formula V, VI {n, m are 0W5; Y is formula VII where M is H, alkali metal, alkaline earth metal, ammonium}) to react with the active groups in the presence of a radical initiator or under ultraviolet irradiation or high-temperature pyrolysis.
