Abstract

PURPOSE: To prepare the titled membrane capable of keeping excellent electrolytic capability stably for a long period, easily and economically, by coating a membrane of a sulfonic acid group-containing fluorine-type copolymer having specific structure with a carboxyl-containing polymer.
CONSTITUTION: The objective ion exchange membrane consists of the first layer composed of a fluorine-type polymer membrane containing the recurring units of formulaI(L is F, CF3, etc.) and formula II (K is 0 or 1; M is H, metal or NH3 +) wherein the ratio ofI/II is 1.5W14, the second layer composed of a polymer containing the recurring units of formula III (L' is L) and formula V (M' is M) wherein III/V is 1.5W14, and an intermediate layer interposed between the first and the second layers and containing randomly distributed sulfonic acid group-containing units having the structure of formula II and carboxylic acid group-containing units having the structure of formula V. The objective membrane can be prepared by applying a solution of a polymer containing the recurring units of formula III and formula IV (Y is 0 or 1; T is 1W4; M" is M or 1W5C alkyl) wherein the ratio of III/IV is 1.5W14 to one surface of the first polymer membrane, and hot-pressing the laminate.
