Abstract:
1. Crosslinked macromolecular material obtained by polymerization or copolymerization of a compound carrying at least two CF 2 ═CF— groups, wherein a negative charge is highly delocalized, said compound corresponding to the formula [CF 2 ═CF-A − ] m M m+ in which: M A is an anionic group having one of the formula (I) [—(CF n and n′ represent 0 or 1; Φ represents a condensed or noncondensed aromatic group, which may or may not carry one or more substituents and which may or may not comprise heteroatoms, or a polyhalogenated group —C Z represents —O or one of the —NC≡N, —C(C≡N) D represents a single bond, an oxygen atom, a sulfur atom, a —CO— carbonyl group or an —SO the groups X R represents Y, YO—, YS—, Y Y represents H or a monovalent organic radical having from 1 to 16 carbon atoms chosen from alkyl, alkenyl, oxaalkyl, oxaalkenyl, azaalkyl, azaalkenyl, aryl or alkylaryl radicals or from the radicals obtained from the abovementioned radicals by substitution, in the chains and/or the aromatic part, by heteroatoms, such as halogens, oxygen, nitrogen, sulfur or phosphorus, it being understood that, if sulfur or phosphorus are present, they can optionally be bonded to substituted nitrogen or oxygen atoms, or else Y is a repeat unit of a polymeric backbone.
