Abstract
PURPOSE: To prepare a fluorinated polymer useful as an ion exchange membrane for the electrolysis of brine, by carrying out aqueous emulsion polymerization of a fluorinated ethylenic monomer and a carboxyl group-type functional monomer in the presence of a specific fluorine-containing surface active agent.
CONSTITUTION: A fluorinated polymer is prepared by copolymerizing (A) a fluorinated ethylenic monomer [pref. I (Z and Z' are F, H or CF3)] with (B) a carboxyl group-type functional monomer [pref. II (l is 0W3, m is 0W1, n is integer of 0W12; X is F or CF3; Y and Y' are F or 1W10C perfluoroalkyl group; A is CN, COF, COOH, etc.)] in the presence of a polymerization initiator, e.g. ammonium persulfate, etc., and an 8C perfluoroalkyl group-containing compound as a fluorine-containing surface active agent (e.g. III, etc.) to attain the (B) content of 5W30mol%.
