摘要： In performing melt processing of a fluorinated polymer which contains such pendant functional groups as sulfonic acid, carboxylic acid, sulfonamide and salts thereof, an aqueous medium is allowed to be present in the polymer to improve its melt-flow characteristic. Excellent heat sealing can be effected without degradation of the polymer. This method is particularly suitable for repairing the damaged ion-exchange membranes of fluorinated polymers used in the electrolysis of sodium chloride to enable elongation of their life to a great economical advantage.

摘要： A fluorinated cation exchange membrane characterized by the gradual decrease in proportion of the density of carboxylic acid and/or carboxylate groups relative to the total density of carboxylic acid and/or carboxylate groups and sulfonic acid and/or sulfonate groups from one surface of the membrane to the other surface or an internal plane therewithin. The cation exchange membrane of the present invention can be prepared by treating one surface of a membrane comprising a fluorocarbon polymer containing pendant groups of the formula:--OCF.sub.2 CF.sub.2 SO.sub.2 Xwherein each X independently is fluorine, chlorine, bromine, hydrogen, ammonium, a quaternary ammonium or a metal atom, with a treating agent having a reducing activity in the presence of a reaction controlling agent selected from carboxylic acids, sulfonic acids, alcohols, nitriles and ethers. The cation exchange membrane of the present invention has an excellent performance in use for electrolysis and can be used stably under severe electrolysis conditions for a long period of time without bringing about partial cleavage or peeling-off, cracking and/or blistering of the carboxylic acid group-richer surface layer thereof.
