Abstract
The invention relates to copolymers, a process for preparing them and their use for the production of ionically conductive materials. The copolymers consist of identical or different organic blocks A which cannot be crosslinked by a radical route or by a Diels-Alder reaction, each of which has a valency i such that 1.ltoreq.i.ltoreq.6, and identical or different blocks Z(CH.sub.2).sub.j, in each of which Z denotes an organic radical which has a valency j such that 1.ltoreq.j.ltoreq.6, the radicals Z additionally containing at least one functional group permitting crosslinking by a radical route or by a Diels-Alder reaction; each block being joined to at least one other block by a functional group Y, the functional group Y being an ether functional group or a secondary or tertiary amine functional group. They are obtained by polycondensation of HYAYH monomers and Z(CH.sub.2 X).sub.j monomers, wherein Y is a leaving group. They are useful in the production of ionically conductive materials.
