Abstract

PURPOSE: To prepare a cast membrane of a sulfonated vinylidene fluoride polymer having low electrical resistance and useful as an ion exchange membrane, etc., and to obtain a uniformly sulfonated vinylidene fluoride polymer easily, by sulfonating the polymer in a powdery state.
CONSTITUTION: A vinylidene fluoride polymer is dispersed in a dispersing medium such as chloroform, etc., and is sulfonated with chlorosulfonic acid (pref. 10W100cc per 10g of the polymer powder and 50W200cc of the dispersing medium). The sulfonated polymer is dissolved in a solvent such as methyl formamide, etc., and cast to obtain a membrane.
