Abstract

PURPOSE: To prepare the titled exchange membrane capable of keeping excellent characteristics for a long period even under severe conditions, by terpolymerizing specific three components such as sulfur-containing fluorinated vinyl compound having a specific structure, etc. at specific ratios, forming the terpolymer to a film, and converting specific convertible group.
CONSTITUTION: A terpolymer obtained by the polymerization of a fluorinated olefin of formulaI(L is F, CF3, etc.), a sulfur-containing fluorinated vinyl compound of formula II (k is 0 or 1; Y is 1W10C alkyl, Cl, etc. when Z is S, and Y is the group defined above, OM or 1W10C perfluoroalkyl when Z is S; M is H, metal, etc.) and a fluoroinated vinyl compound of formula III (l is 0 or 1; m is 2W4; X is COOH, etc.) having carboxylic acid (-convertible) group is formed to a film, and the sulfonic acid convertible group and carboxylic acid convertible group are converted to sulfonic acid group and carboxylic acid group to obtain a perfluorocarbon cation exchange membrane consisting of a copolymer composed of the recurring units of formula IV, formula V and formula VI wherein the ratio of IV/(V+VI) is 1.5W14 and that of VI/V is 0.25W4.
