Abstract

The invention relates to oxyalkylene-group-containing organosilicon compounds having units of the formula ##STR1## where R is identical or different, and denotes a monovalent halogenated or nonhalogenated hydrocarbon radical, X is identical or different and is a chlorine atom or a radical of the formula --OR.sup.1, where R.sup.1 denotes an alkyl radical which can be substituted by an ether oxygen atom, PA1 a is 0 or 1, PA1 b is 0, 1, 2 or 3, PA1 c is 0, 1, 2 or 3 and the total a+b+c.ltoreq.4 and PA1 A is a radical of the formula ##STR2## where R.sup.2 signifies an unbranched or branched substituted or unsubstituted divalent hydrocarbon radical, which may or may not contain ether, amine, sulfide, ester, amide, carbonate, urea and urethane groups, B is identical or different, and denotes X, --NR.sub.2.sup.1, --O--C(.dbd.O)--R.sup.1, --SR.sup.1 or a radical of the formula EQU --NR.sup.3 R.sup.2 [O--CH(CH.sub.3)--CH.sub.2 ].sub.d [OCH.sub.2 CH.sub.2 ].sub.e [O(CH.sub.2).sub.4 ].sub.f OR.sup.4 (III), PA2 where X, R.sup.1 and R.sup.2 have the meanings given for these above, R.sup.3 is identical or different and is a hydrogen atom or has the meaning of R, R.sup.4 has the meaning of R.sup.…
