SULFOALKYLATED POLYSULFONE-BASE ION-EXCHANGE RESIN AND ION-EXCHANGE MEMBRANE CONTAINING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide an ion-exchange resin useful as a polymer electrolyte membrane, especially a polysulfone-base ion-exchange resin containing sulfoalkyl group and having high durability to heat, acid and organic solvent and provide a membrane of the resin. PSOLUTION: The ion-exchange resin is produced by bonding a sulfoalkyl group (III) as an ion-exchange group to a polysulfone having a structural unit expressed by structural formula (I) or a polysulfone having a structural unit expressed by structural formula (II). The invention further provides a membrane produced from the resin. PCOPYRIGHT: (C)2004,JPO
