Abstract

Organosiloxane compounds bearing nitrogen-containing heterocycles, in which the heterocycles are bonded to a silicon atom via divalent radicals containing a unit of the general formula (I) ##STR1## in which E is one of the radicals --O--, --S--, --NR.sup.1 -- or --N.dbd., where R and R.sup.1 are each a C.sub.1 - to C.sub.20 -hydrocarbon radical which is optionally substituted by halogen, amine, ammonium or mercapto groups and may optionally be interrupted by groups chosen from --C(O)--, --C(O)--O--, --C(O)--NR.sup.3 --, --NR.sup.3 --, --O--, --S--, and PA1 --N.dbd. is a constituent of a heterocycle, can be used for the treatment of textile fibers, textile sheet materials and leather and as stabilizers in synthetic polymers.
