Perhalogenated sultone-derived monomers, a preparation method therefor, polymers produced therefrom, and uses thereof for producing ionically conductive materials. The monomers are cpmpounds having the following formula: A-CFX-SO2Z, wherein A is a R3-O-CF2- or R3- or R'R2N-CO- group; Z is F, Cl, -OSi(CH¿3?)3 or an ionic grouping, and is other than F when A is R?3-O-CF¿2- or R3-; X is F, Cl, H or R¿F?, and X is RF when A is R?3¿-; the radicals R', R?2 and R3¿ are chosen from polymerizable non-perfluorinated organic radicals; and R¿F? is chosen from perfluoroalkyl and perfluoroaryl radicals. Polymers produced from said monomers may be used for producing ionically conductive materials.

Compositions à base de dérivés de silice modifiée par des groupements organiques, caractérisées par le fait que lesdits dérivés sont des solides amorphes, que lesdits groupements organiques, présents à raison de 1 à 2, en moyenne, par atome de silicium, sont des groupements poly-oxyalkylène inférieur, et que lesdites compositions contiennent éventuellement des agents dopants; leur préparation par un procédé de type sol-gel; et leur utilisation comme agents de transmission des ondes électromagnétiques et/ou des courants électriques.
摘要:
A polyorganosiloxane-based membrane comprising sulphobenzyl siloxane units and optionally siloxane units having a cross-linking substituent or precursor of a cross-linking grouping, and/or siloxane units having one or two substituents modifying the mechanical properties. The preparation of the membrane and its use, particularly as a solid ion conductor or as an ion exchange resin, are also described.
