Procedure
10 mass % of chloromethyl styrene and 20 mass % of triethyl amine. were reacted in acetone solvent at 40° C. for 40 hours to obtain N,N,N-triethyl(vinylphenyl)methyl ammonium chloride. This was cooled to −5° C., recrystallized and isolated, followed by dissolving the same in toluene at a concentration of 10 mass %, and 0.005 mass % of 2,2-azobis(2-methyl butyronitrile) was further dissolved therein. After nitrogen bubbling, this solution was subjected to polymerization at 50° C. for 72 hours. The solution after polymerization was reprecipitated by pouring the same in excessive amounts of methanol followed by drying to obtain a solid matter. This solid matter was dissolved in tetrahydrofuran at a concentration of 40 mass %, and the solvent was dried after impregnation of porous membrane (polyethylene-based, having weight average molecular weight of 250,000, membrane thickness of 25 μm, average pore diameter of 0.03 μm and porosity of 37%). This operation was repeated several times to produce an anion-exchange membrane 5 including a quaternary ammonium group having a halogeno ion as its counterion.
