Abstract
PURPOSE: To readily form a cation exchanging diaphragm having carbonylic acid group and sulfonic acid group without a process through chemically unstable sulfonic acid group by converting a part of sulfonic acid group of side chain of a vinylfluoride copolymer into a carboxylic acid group through an atomic groupOCF2CF2X (X;halogen).
