Title:
PROTON-CONDUCTIVE POLYMER ELECTROLYTE FILM HAVING EXCELLENT OXIDATION RESISTANCE, AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/066773
Kind Code:
A1
Abstract:
This process for producing a proton-conductive polymer electrolyte film comprises the steps of: irradiating resin microparticles with a radioactive ray; graft-polymerizing a vinyl monomer having a sulfonic acid group precursor and a vinyl monomer having a carbonyl group equivalent onto the resin microparticles in a solid-liquid dual phase system to produce microparticulate graft polymer; preparing a cast solution comprising a polymer having a phosphoric acid group or a phosphonic acid group and the graft polymer and forming a cast film from the solution; drying the cast film to produce a film; converting the sulfonic acid group precursor into a sulfonic acid group; and forming a cross-liked structure between the carbonyl group equivalents. In the solid-liquid dual phase system, a liquid phase comprises a vinyl monomer and a solvent for the vinyl monomer and a solid phase comprises resin microparticles. The process enables to provide: a proton-conductive polymer electrolyte film having high oxidation resistance; and a process for producing the film on an industrial scale.
