PROBLEM TO BE SOLVED: To provide a new polymer material which can be a polymer electrolyte with not only good solvent resistance, durability, stability but also good ion conductivity by adding sulfonic acid group to a polymer of polyimidazole system which is good in heat resistance, solvent resistance and in mechanical characteristics, or the like. SOLUTION: Polyimidazole containing sulfonic acid group has main ingredients expressed in formulae (1), (2), In the formulae, X stands for -O-, -SO2-, -C(CH3)2-, -C(CF3)2-, and -OPhO-, Ar stands for an aromatic group, m stands for figures from 1 to 4 and n stands for figures of not less than 0.2 and not more than 1.0. By introducing the sulfonic acid group to a polymer of polyimidazole system having such excellent qualities as heat resistance, solvent resistance and good mechanical characteristics, or the like, a new polymer electrolyte is obtained, which can be a good polymer electrolyte not only with good solvent resistance, durability and stability but also with good ion conductivity. |
