Use of Perfluoromethanesulfonyl Peroxides to Produce Fluoropolymers F-4SF and Ion-Exchange Membranes Based on Them

Resumo

Perfluoromethanesulfonyl peroxides were prepared for the first time using intermediates and wastes from producing perfluorinated sulfonyl fluoride, one of the reagents for preparing the copolymer precursor of ion-exchange membranes. These perfluoroperoxides were used radical copolymerization initiators for fluoroorganic compounds. Copolymers with given characteristics were synthesized by casting a solution of the copolymers to form membranes with several characteristics exceeding those of Nafion membrane (DuPont).
