Abstract
PURPOSE: To produce an anion exchange membrane low in impurity content and capable of being used in the regeneration of color developers, by washing an anion exchange membrane with a buffer solution having a specified pH.
CONSTITUTION: A vinylpyridine monomer of formulaIWIII, wherein R is H, CH3, C2H5 or C3H7, or a basic vinyl monomer of formula IV, wherein R1 or CH3, R2 and R3 are each H, CH3, C2H5, n-C3H7, CH(CH3)2 or n-C4H9 and n is 1W10, a prim. to tert. amine and a haloalkyl or haloaryl group-containing compound, e.g., methyl iodide, are copolymerized or graft-polymerized with a polyolefin membranous product. The amine groups of the copolymer or the graft polymer are quaternized to obtain an anion exchange membrane. This membrane is washed in countercurrent contact with a buffer solution, pH 9W12, e.g., boric acid/KCl/NaOH solution.
