Abstract
The present invention relates to copolymers, to a process for their preparation and to their use for the production of ionically conductive materials. A copolymer according to the invention consists of monomer units corresponding to the formula --CH.sub.2 --O--CHR--CH.sub.2 O (I) and monomer units corresponding to the formula --CH.sub.2 --CHR'--O-- (II), in which: R denotes a hydrogen atom, a linear or branched alkyl radical containing from 1 to 8 carbon atoms or a radical CH.sub.3 (--O--CH.sub.2 --CH.sub.2).sub.n --O--CH.sub.2 --, in which 1.ltoreq.n.ltoreq.10; R' denotes an aliphatic radical containing an unsaturation which can be polymerized by a radical route and inert in the conditions of cationic polymerization. The copolymers can be obtained by cationic polymerization of the appropriate oxirane and dioxolane. Application to the production of ionically conductive materials.
