Abstract

Oraganopolysiloxanes of the general formula ##STR1## where R.sup.1 =identical or different aliphatic or aromatic hydrocarbon radicals, PA1 R.sup.2 =CH.sub.2 CH.sub.2 O(CR.sup.4 R.sup.5).sub.x OC(O)CR.sup.6 .dbd.CHR.sup.7, where PA2 R.sup.4, R.sup.5, R.sup.6 and R.sup.7 PA3 can be identical or different radicals and are each a H or alkyl radical, branched or unbranched, having up to a total of 6 C atoms and x has a value from 3 to 11, where --(CR.sup.4 R.sup.5)-- can also be a cyclic aliphatic or aromatic radical, PA1 R.sup.3 =R.sup.2 or R.sup.1, PA1 a=0 to 50 and PA1 b=0 to 500, PA1 but at least one radical R.sup.2 is attached terminally and/or laterally.
