Di-functional monomers of general formula ¢T~SO2~Y~SO2T'!-M+ where: - T or T' are identical or different and each represent an organic radical having at least one polymerization-active function; - M+ represents a cation, inorganic or organic, preferably chosen among: H+, Li+, Na+, K+, 1/2Mg2+, 1/2Ca2+, 1/2Ba2+, 1/2Zn2+ and other transition metals, 1/3La3+ and other rare earths, ammonium, amidinium, pyridinium, imidazolium, guanidinium, sulfonium, phosphonium, iodonium, organometallic cations, all possibly including coordination ligands.... - Y represents N (nitrogen), CH, or CQ. - Q represents an alkyl or alkylene with 1 to 20 carbons, halogenated or not, possibly having aza or oxa substituents, or T or an alkyl- or an alkylene- sulfonyl group, with 1 to 20 carbons, halogenated or not, possibly having aza or oxa substituents. |
