Abstract:
An organosilicon compound containing (meth)acrylate groups and oxyalkylene groups and comprising units of the formulaA.sub.a A'.sub.u R.sub.b SiX.sub.c O.sub.(4-a-b-c-u)/2 (I),whereR can be identical or different and are each a monovalent, SiC-bonded, substituted or unsubstituted hydrocarbon radical having from 1 to 22 carbon atoms, X are identical or different and are each a radical of the formula --OR.sup.1 where R.sup.1 is a hydrogen atom or an alkyl radical having from 1 to 8 carbon atoms in which ether oxygen atoms may be present, or a radical of the formula--R.sup.2 {[CH(CH.sub.3)CH.sub.2 O].sub.e [CH.sub.2 CH.sub.2 O].sub.f [(CH.sub.2).sub.4 O].sub.g R.sup.3 }.sub.y-1 (II)where R.sup.2 is an SiC-bonded divalent or trivalent hydrocarbon radical having from 2 to 60 carbon atoms which may be interrupted by one or more oxygen atoms and is substituted by one or more groups of the formulae ##STR22## --NHR.sup.3 --, and --S--, y is, corresponding to the valence of radical R.sup.2, 2 or 3, R.sup.3 is a hydrogen atom or a hydrocarbon radical having from 1 to 20 carbon atoms which may be substituted by a --C(O)-- group, and e, f and g are each, independently of one another, 0 or an integer from 1 to 200, with the proviso that the sum e+f+g.gtoreq.1,A is a radical of the formula ##STR23## where R.sup.4 is a divalent or trivalent hydrocarbon radical having from 2 to 60 carbon atoms which may be interrupted by one or more oxygen atoms, x is, corresponding to the valence of radical R.sup.4, 2 or 3, Z is a radical --O-- or --NR.sup.3 -- where R.sup.3 is as defined above and R.sup.5 is a hydrogen atom or a methyl group,A' is a radical of the formula ##STR24## where R.sup.9 is a trivalent hydrocarbon radical having from 2 to 60 carbon atoms which may be interrupted by one or more oxygen atoms, R.sup.10 is a divalent hydrocarbon radical having from 2 to 20 carbon atoms which may be interrupted by one or more oxygen atoms and is substituted by one or more groups of the formulae ##STR25## --NHR.sup.3 --, and --S--, and R.sup.5, R.sup.3, e, f and g are as defined above,a is 0, 1 or 2,u is 0, 1 or 2,b is 0, 1, 2 or 3 andc is 0, 1, 2 or 3,with the proviso that the sum a+b+c+u.ltoreq.4 and the organosilicon compound contains at least one radical A and at least one radical of the formula (II), or at least one radical A' per molecule.
