Document Type and Number:
Japanese Patent JP4725761
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a solid polymeric electrolyte having excellent oxidation resistance simply and at a low cost while maintaining the safety on production. SOLUTION: The method for producing a solid polymeric electrolyte is constituted by comprising a halosulfonation step of introducing sulfonyl halide groups into a hydrocarbon based polymer to obtain a halosulfonated hydrocarbon based polymer; a chelating functional group introduction step of dipping the above halosulfonated hydrocarbon based polymer in a reactive chelate compound solution obtained by dissolving or dispersing a compound having a reactive functional group and a chelating functional group in a solvent and reacting the reactive functional group with part of the above introduced sulfonyl halide groups to form chemical bonds therein to introduce the chelating functional groups; and a sulfonic group introduction step of dipping the above chelating functional group-introduced halosulfonated hydrocarbon based polymer in a hydrolyzing liquid and hydrolyzing the rest of the above introduced sulfonyl halide groups to form sulfonic groups.
