| 摘要 |
The invention relates to organopolysiloxanes comprising quaternary ammonium groups, comprising units of the general formula QRSiOERSiOand RSiO, wherein R is the same or various and means and a univalent, optionally halogenated hydrocarbon radical having 1 to 18 carbon atoms, E means a univalent SiC-bonded organic radical having 3 to 18 carbon atoms and comprising an epoxy group, Q means a univalent SiC-bonded organic radical, in which a quaternary ammonia group is bonded to a silicon atom by means of an opened-ring epoxy group, a is equal to 0, 1, or 2, b is equal to 0, 1, or 2, and c is equal to 0, 1, 2, or 3, under the stipulation that the organopolysiloxanes each comprise at least one unit of the formulas and and the ratio of the radicals Q/E lies, on average, in the range from 0.2 to 100, preferably from 0.5 to 20, preferably from 1 to 10.
