    摘要： A sulfonated aromatic polyether useful for an electrolyte membrane superior in the properties such as conductivity and stability which has a principle backbone represented by the general formula (1). wherein Ar1 and Ar2 are defined C6-20 groups containing aromatic ring(s), x and y are each an integer of 0 to 3 which represent the degree of sulfonation, with the proviso that the case where both of x and y are simultaneously 0 is excluded, and n and m are each an integer of not lower than 2 which represent the degree of polymerization In the sulfonated aromatic polyether, the sites of introduction of the sulfonic acid groups are strictly specified, and the aromatic rings in the main chain has no sulfonic acid group at all, therefore, it is advantageous in that both of proton conductivity at higher than 100° C. and oxidative and hydrolytic stability are superior.

    摘要： A polyimide resin having a basic skeleton represented by the following general formula: (in the formula (1), each of Ar1 and Ar2 is an aromatic ring having a carbon number of 6-20, which forms an imide ring of 5 or 6 atoms with an imide group adjoining thereto. In the aromatic ring, a part of carbon atoms may be substituted with S, N, 0, SO2 or CO, or a part of hydrogen atoms may be substituted with an aliphatic group, a halogen atom or a perfluoro aliphatic group. Ar1 and Ar2 may be same or different. R is at least one of linear alkylene group and branched alkylene group having a carbon number of 1-20. Ar3 is an aromatic ring having a carbon number of 6-20 in which at least a part of hydrogen atoms is substituted with at least one of sulfoalkoxy group, carboalkoxy group and phosphoalkoxy group having a carbon number of 1-20 and a part of carbon atoms in these groups may be substituted with S, N, 0, SO2 or CO, or a part of hydrogen atoms may be substituted with an aliphatic group, a halogen atom or a perfluoro aliphatic group. n and m show a polymerization degree and are an integer of not less than 2.)
