Abstract: PROBLEM TO BE SOLVED: To provide a ion conductive film which is prepared from a polymer suitable for use as a polymer solid electrolyte, having sufficient chemical stability and soluble in a proper solvent. SOLUTION: A crosslinkable sulfonic acid polymer represented by formula (VII) and a polymer electrolyte film obtained from the same are provided, (a is a number from 0.15 to 0.95: b is a number from 0.05 to 0.25; c is a number from 0 to 0.8; a+b is a number from 0.2 to 1.0; a+b+c is 1; R1 is a group selected from the group represented by the formula).

Abstract: PROBLEM TO BE SOLVED: To provide chemically, electrically and dynamically stable macromolecular solid electrolyte film. SOLUTION: Macromolecular electrolyte film of material provided by sulfonating aromatic polyether ketone shown by a chemical formula I is used for proton conductive solid electrolyte film in a fuel cell or electrolytic cell (Here, Ar is phenylene ring including p- and/or m-bond, Ar' is phenylene, naphthalene, biphenylene, antrylene or other bivalent aromatic structure unit, X, N and M are individual each other and 0 or 1, Y is 0, 1, 2 or 3, P is 1, 2, 3 or 4).

Abstract: "Polymer electrolyte membrane, and process for the production thereof" In order to produce a polymer electrolyte membrane from sulfonated, aromatic polyether ketone, an aromatic polyether ketone of the formula (I) in which Ar is a phenylene ring having p- and/or m-bonds, Ar' is a phenylene, naphthylene, biphenylene, anthrylene or another divalent aromatic unit, X, N and M, independently of one another are 0 or 1, Y is 0, 1, 2 or 3, P is 1, 2, 3 or 4, is sulfonated and the sulfonic acid is isolated. At least % of the sulfonic groups in the sulfonic acid are converted into sulfonyl chloride groups, and these are reacted with an amine containing at least one crosslinkable substituent or a further functional group, and unreacted sulfonyl chloride groups are subsequently hydrolyzed. The resultant aromatic sulfonamide is isolated and dissolved in an organic solvent, the solution is converted into a film, and the crosslinkable substituents in the film are then crosslinked. In specific cases, the crosslinkable substituents can be omitted. In this case, sulfonated polyether ketone is converted into a film from solution.

Abstract: In order to produce a polymer electrolyte membrane from sulphonated aromatic polyether ketone, an aromatic polyether ketone of the formula (I) where Ar is a phenylene ring having p- and/or m-bonds, Ar' is a phenylene, naphthylene, biphenylene, anthrylene or another divalent aromatic unit, X, N and M, independently of one another, are 0 or 1, Y is 0, 1, 2 or 3, P is 1, 2, 3 or 4, is sulphonated, and the sulphonic acid is isolated. At least 5 % of the sulphonyl groups in the sulphonic acid are converted into sulphonyl chloride groups, and these are reacted with an amine which has at least one crosslinkable substituent or a further functional group, and unreacted sulphonyl chloride groups are subsequently hydrolysed. The resultant aromatic sulphonamide is isolated and dissolved in an organic solvent, the solution is converted into a film, and the crosslinkable substituents present in the film are then crosslinked. In specific cases, the crosslinkable substituents can be omitted. In this case, sulphonated polyether ketone is converted into a film from solution.
