Abstract

Organosilicon compounds containing (meth)acrylate groups and oxyalkylene groups and comprising units of the formula EQU A.sub.a A'.sub.u R.sub.b SiX.sub.c O.sub.(4-a-b-c-u)/2, (I) where R is as defined in claim 1, 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 EQU --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, R.sup.3, e, f, g and y are as defined in claim 1, A is a radical of the formula ##STR1## where R.sup.4, R.sup.5 and x are as defined in claim 1, A' is a radical of the formula ##STR2## where R.sup.3, R.sup.5, R.sup.9, R.sup.10, e, f and g are as defined in claim 1, a is 0, 1 or 2, u is 0, 1 or 2, b is 0, 1, 2 or 3 and c 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.
