An inexpensive and durable polyelectrolyte composition includes both an aromatic polymer containing carbonyl linkages and/or sulfonyl linkages in the backbone chain and bearing cation-exchange groups and a fused salt exhibits a high ionic conductivity even in the absence of water or a solvent. The aromatic polymer is preferably an aromatic polyether sulfone comprising specific structural units and bearing cation-exchange groups, an aromatic polyether ketone comprising specific structural units and bearing cation-exchange groups, an aromatic polyether sulfone block copolymer consisting of at least one hydrophilic segment bearing cation-exchange groups and at least one hydrophobic segment free from cation-exchange groups, and/or an aromatic polyether ketone block copolymer consisting of at least one hydrophilic segment bearing cation-exchange groups and at least one hydrophobic segment free from cation-exchange groups. The use of such a block copolymer as the aromatic polymer gives polyelectrolyte compositions which are excellent in maintenance of structure even at high temperature.
An inexpensive and durable polymer electrolyte composition exhibiting high ionic conductivity even in the absence of water or a solvent, characterized by comprising a molten salt and an aromatic polymer having a carbonyl bond and/or a sulfonyl bond in the main chain thereof and containing a cation exchange group. The aromatic polymer is preferably an aromatic polyether sulfone having a specific structural unit and containing a cation exchange group, an aromatic polyether ketone having a specific structural unit and containing a cation exchange group, or an aromatic polyether sulfone block copolymer and/or an aromatic polyether ketone block copolymer, the block copolymers comprising a hydrophilic segment containing a cation exchange group and a cation exchange group-free hydrophobic segment. The polymer electrolyte composition containing the block copolymer as an aromatic polymer exhibits high structural retention even in high temperatures.

Tough crystalline thermoplastic aromatic polyetherketones containing the repeat units
alone or in conjunction with other repeat units especially
and having an inherent viscosity IV of at least 0.7, preferably at least 0.8. The polymers may be made by condensation of hydroquinone, 4,4'-difluorobenzophenone and an alkali metal carbonate or bicarbonate in the presence of an aromatic sulphone solvent, e.g. diphenyl sulphone, at 150-400°C. The polymers are very useful for wire coating. The most relevant I prior art techniques for making polyetherketones produce low molecular weight polymer when applied to this system.
