Ionic organosilicon compounds comprising siloxane units of the formula AaRbXcSiO(4-a-b-c)/2 (I), in which R is an identical or different, optionally halogenated hydrocarbon radicals having 1 to 12 carbon atoms or radicals of the formulae -R'-((NHCH2CH2)o-(N+H2CH2CH2)p-N(x+q-2)+HXR'' q) d-1 (II), -R'-(SH) d-1 (III) or -R'-(Z-C(O)-CR'''=CH2) d-1 (IV) in which R', R'', Z, R''', o, p, q, x, d, X and A have the meaning given in claim 1 and a is 0 or 1, b is 0, 1, 2 or 3, c is 0, 1, 2 or 3 and the sum a+b+c is ~ 4, with the proviso that at least one radical A is contained in each molecule, and, optionally, non-bonding counter-ions from the group consisting of alkali metal, alkaline earth metal and ammonium ions of organic amines are present to compensate the negative charges and non-bonded counter-ions from the group consisting of organic anions, such as, for example, acetate ions, are present to compensate the positive charges,their preparation and their use.

Composés organosiliciés ioniques comprenant des unités siloxane de formule AaRbXcSiO(4-a-b-c)/2 (I), où R est un radical hydrocarboné identique ou différent, facultativement halogéné, de 1 à 12 atomes de carbone ou un radical de formules -R'-((NHCH2CH2)o-(N+H2CH2CH2)p-N(x+q-2)+HXR'' q) d-1 (II), -R'-(SH) d-1 (III) ou -R'-(Z-C(O)-CR'''=CH2) d-1 (IV) où R', R'', Z, R''', o, p, q, x, d, X et A ont les significations données dans la revendication 1 et a est 0 ou 1, b est 0, 1, 2 ou 3, c est 0, 1, 2 ou 3 et la somme a+b+c est ~ 4, à la condition qu'au moins un radical A soit contenu dans chacune des molécules, et, facultativement, que des contre-ions non liants du groupe constitué des ions de métal alcalin, de métal alcalino-terreux et d'ammonium d'amines organique soient présents pour compenser les charges négatives et que des contre-ions non liés du groupe constitué des anions organiques comme, par exemple, les ions acétate, soient présents pour compenser les charges positives; préparation et utilisation de ces composés.
