Abstract

The new compounds have the formula below ##STR1## in which R.sub.f is a perfluoroalkyl radical having 4 to 20 carbon atoms, PA0 x is 1 to 4, PA0 y is 1 to 10, PA0 X is Br, Cl or I, and PA0 R.sup.1 and R.sup.2 are hydrogen or a C.sub.1 to C.sub.4 -alkyl radical or a water-solubilizing aliphatic radical, with the proviso that at least one of the two substituents R.sup.1 and R.sup.2 is a water-solubilizing aliphatic radical. The surface-active compounds described are prepared by reacting a suitable epoxide with a suitable amine. They are used in particular for the preparation of foaming agents.
