PURPOSE:To prepare an anion-exchange membrane which is useful for various electrolytic diaphragms and excellent in durability and electric current efficiency, by causing a film consisting of a specified polymer to react with a mixture of two different amines, and then, if necessary, with an alkali metal hydroxide, and finally with an alkyl iodide. CONSTITUTION:A mixture of amines B is obtd. by mixing an amine of formula I (where r is 2-5) and an amine of formula II (where r' is r, and R1-2 are 1-5C alkyl groups) in a vol. ratio of 0.5/99.5-30/70 and, if necessary, adding a solvent such as diethyl ether, toluene, etc. thereto. A plain or tubular film A consisting of a polymer having a structure of formula III (where X is F, CF3; l is 0-5; m is 0, 1; n is 1-5; p and q are both integers and p/q=2-16) is caused to react with the component B at room temp. to 80 deg.C and then, if necessary, with an alkali metal hydroxide C at room temp. to 90 deg.C and finally with a 1-5C alkyl iodide D. |
