    摘要: A vinyl monomer is graft polymerized on an aromatic hydrocarbon-based polymer film substrate to introduce graft chains into the substrate and thereafter a functional monomer represented by the following formula and having sulfonic acid groups or functional groups capable of conversion to sulfonic acid groups is graft polymerized to introduce the sulfonic acid groups or the functional groups capable of conversion to sulfonic acid groups: where R is an aromatic ring or an aliphatic chain; X is (1) —OH, (2) —OLi, —ONa or —OK, (3) —F or —Cl, or (4) —OCnH2n+1 where n is an integer of 1 to 7. Since the graft chains obtained by graft polymerization of the vinyl monomer can also be utilized as scaffold polymers, the graft polymerizability of the functional monomer to the aromatic hydrocarbon-based polymer film substrate is sufficiently improved to enable the preparation of a polymer electrolyte membrane that excels not only in proton conductivity and mechanical strength but also in dimensional stability.

    摘要: An aromatic polymer film substrate, or a grafted aromatic polymer film substrate having a monomer introduced therein as graft chains is irradiated with ionizing radiation to impart a crosslinked structure. The aromatic polymer film substrate or the grafted aromatic polymer film substrate, provided with the crosslinked structure, is directly sulfonated to obtain a crosslinked aromatic polymer electrolyte membrane. The crosslinked aromatic polymer electrolyte membrane has low water uptake, high proton conductivity, low methanol permeability, high chemical stability, and excellent mechanical characteristics.

    摘要: The process for producing a proton conductive polymer electrolyte membrane of the present invention includes the steps of: irradiating resin fine particles with radiation; graft-polymerizing a vinyl monomer having a sulfonic acid group precursor and a vinyl monomer having a carbonyl group equivalent with the resin fine particles in a solid-liquid two-phase system to obtain a finely particulate graft polymer; preparing a casting solution of a polymer having a phosphoric acid group or a phosphonic acid group and the graft polymer, and forming a cast membrane from this solution; drying the cast membrane to obtain a film; converting the sulfonic acid group precursor into a sulfonic acid group; and forming a crosslinked structure between the carbonyl group equivalents. In the solid-liquid two-phase system, a liquid phase includes the vinyl monomers and a solvent for the monomers, and a solid phase includes the resin fine particles. By this process, a proton conductive polymer electrolyte membrane having high oxidation resistance, and a process capable of producing this membrane industrially are provided.
