Abstract

Surface active anion-cation complexes are synthesized where an organic or organosilicon compound with at least one epoxide group is reacted with a quaternary ammonium hydrogen sulfite of the general formula EQU HN.sup.+ (R.sup.1).sub.3 SO.sub.3 H.sup.- I wherein R.sup.1 within the molecule is the same or different and can be PA1 (1) an alkyl or hydroxyalkyl group with 1 to 18 carbon atoms, PA1 (2) a phenyl group, or PA1 (3) a group of the formula C.sub.n H.sub.2n+1 CONH--(CH.sub.2).sub.m --, in which n can be a number from 7 to 17 and m is 2 or 3, in the presence of a polar solvent in such amounts so that the molar ratio of the epoxide group to HN.sup.+ (R.sup.1).sub.3 SO.sub.3 H.sup.- is 2:1.
