Abstract
PURPOSE: To provide a fluorine-contg. cation exchange membrane with improved mechanical properties as well as electrochemical properties, obtd. by cross-linking a copolymer of an iodine-contg. vinyl ether, a fluorinated olefin, and a fluorine- contg. monomer having an ion exchange group or a functional group convertible into the ion exchange group.
CONSTITUTION: An iodine-contg. vinyl ether (A) of formula I, e.g. CF2= CFO(CH2)4I, a fluorinated olefin (B) of formula II, e.g. trichlorotrifluoroethane, and a fluorine-contg. monomer (C) of formula III, e.g. CF2=CFOCF2CF(CF3)OCF2 CF2SO2F are copolymerized in the presence of a polymn. initiator such as an azobis cpd. At this time, the components A,C contained are 0.1W10mol% and 1W50 mol%, respectively. The copolymer is then formed into a 20W1000μ thick membrane and cross-linked by a known method used in cross-linking of a usual linear polymer, e.g. radiation of heat or ultraviolet rays to obtain a desired fluorine-contg. cation exchange membrane
