• wherein
• R represents --OH, --OCH.sub.2 --CH.dbd.CH--(CH.sub.2).sub.3 --CH.dbd.CH.sub.2 group, --(R.sup.5).sub.a --R.sup.6 group or --OCH.sub.2 --CH.dbd.CH--(CH.sub.2).sub.5 --R.sub.4 group,
• with the proviso that at least one of the R groups has the last-mentioned meaning,
• R.sup.4 being a silyl group having the formula --SiR.sup.1 R.sup.2 R.sup.3, in which R.sup.1, R.sup.2 and R.sup.3 are the same or different aliphatic or aromatic hydrocarbon groups, or
• a linear or branched organosiloxanyl group with 2 to 200 silicon atoms,
• R.sup.5 is a group having the formula -O(CH.sub.2).sub.b -- or a polyether group having the formula --(OC.sub.n H.sub.2n).sub.c, wherein b has a value of 1 to 11, n has an average value of 2 to 2.5 and c a value of 1 to 2,
