PROBLEM TO BE SOLVED: To obtain a molecular weight equal to or higher than the molecular weight of a hydrocarbon-based polymer electrolyte polymer synthesized by a method according to the related art, even though the reaction time is reduced.SOLUTION: As a polymerization solvent for use in the polymerization of monomers for a hydrocarbon-based electrolyte polymer, a mixed solvent obtained by mixing a first solvent, such as dimethyl acetamide, N-methylpyrrolidone or dimethyl sulfoxide, with a second solvent being an alcohol is used instead of a dimethyl acetamide/toluene mixture or dimethyl acetamide alone according to the related art. Such a method is extremely useful for a mass production of a hydrocarbon-based polymer electrolyte. |
