Monomers derived from perhalogenated sultones and polymers obtained from these monomers

摘要

The invention relates to monomers derived from perhalogenated sultones, to a process for their preparation, to the polymers obtained from the said monomers and to their use for the production of ion-conductive materials. The monomers are compounds corresponding to the formula A-CFX-SO2Z in which A denotes one groups [sic] R3-O-CF2- or R3- or R1R2N-CO-; Z denotes F, Cl, -OSi(CH3)3 or an ionic group, Z being other than F when A denotes R3-O-CF2- or R3-; X denotes F, Cl, H or RF, X being RF when A denotes R3-; the radicals R1, R2 and R3 are chosen from polymerizable nonperfluorinated organic radicals; RF is chosen from perfluoroalkyl radicals and perfluoroaryl radicals. The polymers obtained from these monomers can be employed for the production of ion-conductive materials.
