Abstract

PURPOSE: To easily form ion exchange groups with chemical resistance in the outer layer of a polymer having no ion exchange group by oxofluorinating the polymer, followed by fluorination and treatment with a hot conc. alkali soln.
CONSTITUTION: An olefin type polymer having no ion exchange group or a hydrogen-contg. halogenated olefin type polymer, e.g. a film of emulsion polymn. type polyvinylidene fluoride is oxofluorinated in a reactor with a mixed gas of F2 and O2 in the presence of inert gas. The mixed gas in the reactor is replaced by inert gas and sufficient vacuum degassing is carried out. The product oxyfluoride is then fluorinated with F2 gas contg. O2≤0.1 vol% and the resulting perfluorocarboxylic acid fluoride is brought into contact with a hot soln. of alkali such as NaOH to impart ion exchange activity to the outer layer of the polymer, thus a perfluorocarboxylic acid type cation exchanger being obtd. The concn. of the soln. is desirable to be 6W10 N and the treating temp. 90W100°
