Organosilicon compounds containing amino groups, their preparation and their use

Abstract

Abstract Organosilicon compounds containing amino groups, their preparation and their use Organosilicon compounds containing amino groups and comprising a) siloxane units of the formula R.sub.a Si(OR.sup.1).sub.b O.sub.(4-a-b)/2 (I) and b) at least one unit per molecule selected from the group consisting of units of the formulae AR.sub.C SiO.sub.(4-c-1)/2 (II), O.sub.(4-c-1)/2 R.sub.C Si--A.sup.1 --R.sub.C SiO.sub.(4-c-1)/2 (III) or ##STR1## where R is an identical or different hydrocarbon radical which has from 1 to 18 carbon atoms, optionally substituted by halogen atoms, alkoxy groups or hydroxy groups where the hydrocarbon radical is optionally interrupted by oxygen atoms, R 1 is an identical or different alkyl radical which is optionally interrupted by oxygen atoms, a is 0, 1, 2 or 3 and b is 0, 1, 2 or 3, with the proviso that the sum a+b is not greater than 3, and c is 0, 1 or 2, A is a radical of the formula --R.sup.2 R.sup.3.sub.z N(--CR.sup.4.sub.2 --R.sup.5).sub.(2-z) (V), A 1 is a radical of the formula ##STR2## and A 2 is a radical of the formula ##STR3## where z is 0 or 1, R 2 is an identical or different alkylene radical having from 2 to 8 carbon atoms, or a radical of the formula ##STR4## R 3 is a hydrogen atom or an alkyl radical having from 1 to 8 carbon atoms, R 4 is a hydrogen atom or an alkyl radical having from 1 to 8 carbon atoms, R 5 is a radical of the formulae --CR 6 ═CR 6 2 , --C.tbd.CR 6 , where R 6 is identical or different and is a hydrogen atom or an alkyl radical having from 1 to 8 carbon atoms, with the proviso that the organosilicon compound containing amino groups has at least one siloxane unit of formula (II) per molecule and at least one unit selected from the group consisting of units of formulae (III) and (IV) per molecule.
