Abstract

PURPOSE: To obtain an ion exchange membrane suitable for use as a diaphragm for electrolysis of an aq. soln. of alkali metal salts by treating a polymeric substance, with amines, having C to which a sulfonyl halide group other than sulfonyl fluoride and a F atom are bended, followed by heat treatment.
CONSTITUTION: A membraneous polymeric substance having C to which the above sulfonyl halide group, esp. sulfonyl chloride and a F atom are bonded, e.g. a perfluorocarbon type polymeric substance is reacted with a cpd. having prim. and/or sec. amino groups, e.g. n-butylamine. The reaction product is then heat treated at 50W250°C to form a layer contg. carboxylic acid groups and sulfonic acid amido groups in the polymeric substance. The perfluorocarbon type polymeric substance may be, e.g. a copolymer of tetrafluoroethylene and perfluoro (3,6-dioxa-4-methyl-7- octenesulfonyl halide).
