Abstract:
An organosilicon compound comprising units of the general formula (I)A.sub.a R.sub.b SiX.sub.c O.sub.(4-a-b-c)/2 (I)in whichR is identical or different and is a monovalent hydrocarbon radical which has 1 to 22 carbon atoms optionally substituted by halogen, amino, mercapto or ammonium groups,X is identical or different and is a chlorine atom or a radical of the formula --OR.sup.1,R.sup.1 is a hydrogen atom or an alkyl radical having 1 to 8 carbon atoms optionally substituted by ether-oxygen atoms, or is a radical of the general formula (II)--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.sub.3 }.sub.y-1 (II),in whichR.sup.2 is a divalent, trivalent or tetravalent hydrocarbon radical having 2 to 30 carbon atoms, interrupted by one or more groups of the formulae ##STR9##and which can further be interrupted by oxygen atoms,y is 2, 3 or 4, according to the valency of the radical R.sup.2,R.sup.3 is a hydrogen atom or a hydrocarbon radical which has 1 to 20 carbon atoms and is optionally interrupted by a group --C(O)--,e, f and g independently are 0 or an integer from 1 to 200, with the proviso that the sum of e+f+g.gtoreq.1,A is a radical of the general formula (III)--R.sup.4 {--C(H)C.sub.n (H.sub.2 O).sub.n }.sub.y-1 (III),in whichR.sup.4 has a meaning given for R.sup.2,y is 2, 3 or 4, according to the valency of the radical R.sup.4,n is an integer from 1 to 1,000,000,a is 0, 1 or 2 andb and c in each case are 0, 1, 2 or 3, and when (III) is an oligo- or polysaccharide, one molecule of H.sub.2 O is subtracted from the empirical formula per carbohydrate monomer or polymer added to the formula, or A is a partly reduced, oxidized, or partly dehydrated or organyl-modified derivative of the formula (III),with the proviso that the sum of a+b+c.ltoreq.4 and the organosilicon compound contains at least one radical A per molecule.
