    摘要： It is to provide an electrolyte material with which an increase in the water content can be suppressed even when the ion exchange capacity of a polymer having repeating units based on a monomer having a dioxolane ring is high; and a membrane/electrode assembly excellent in the power generation characteristics under low or no humidity conditions and under high humidity conditions.It is to use an electrolyte material, which comprises a polymer (H) having ion exchange groups converted from precursor groups in a polymer (F), and having an ion exchange capacity of at least 1.35 meq/g dry resin, the polymer (F) having repeating units (A) based on a perfluoromonomer having a precursor group of an ion exchange group and a dioxolane ring and repeating units (B) based on a perfluoromonomer having no precursor group and having a dioxolane ring, and having a TQ of at least 200° C., which is a temperature at which the melt volume rate becomes 100 mm3/sec when the polymer (F) is subjected to melt-extrusion under an extrusion pressure condition of 2.94 MPa from a nozzle having a length of 1 mm and an inner diameter of 1 mm.

    摘要： The present invention provides a polyvinyl acetal-based resin which has a high elastic modulus, is excellent in solubility to an alcoholic solvent, and gives a highly transparent alcohol solution. The polyvinyl acetal-based resin is obtained by acetalizing a polyvinyl alcohol-based resin (A) which has 0.1 to 1.5% by mol of a 1,2-diol structural unit represented by the following general formula (1) and a degree of saponification of 98.5% by mol or more: wherein R1, R2, and R3 each independently represents a hydrogen atom or an organic group; X represents a single bond or a bonding chain; and R4, R5, and R6 each independently represents a hydrogen atom or an organic group.
