Abstract

An aqueous alcoholic fluoroalkyl functional group containing organopolysiloxane- composition, comprising: PA1 organopolysiloxanes of formula I: EQU ROSi(A)(CH.sub.3).sub.z (OR).sub.1-z O!.sub.a Si(B)(R.sup.2).sub.y (OR).sub.1-y O!.sub.b EQU Si(C)(CH.sub.3)O!.sub.c Si(D)(OR)O!.sub.d R.multidot.(HX)(I) wherein A is an aminoalkyl radical derived from the compound of formula II: EQU H.sub.2 N(CH.sub.2).sub.f (NH).sub.g (CH.sub.2).sub.h Si(OR).sub.3-z (CH.sub.3).sub.z (II) wherein 0.ltoreq.f.ltoreq.6, 9=0 if f=0 and g=1 if f>0, 0.ltoreq.h.ltoreq.6 and 0.ltoreq.z.ltoreq.1, and B is a fluoroalkyl radical derived from the compound of formula III: EQU R.sup.1 --Y--(CH.sub.2).sub.2 Si(R.sup.2)y(OR).sub.3-y (III) wherein R.sup.1 is a mono-, oligo- or perfluorinated alkyl group having 1-9 C atoms or a mono-, oligo- or perfluorinated aryl group, Y is a CH.sub.2, O or S group, R.sub.2 is a linear, branched or cyclic alkyl group having 1-8 C atoms or an aryl group and 0.ltoreq.y.ltoreq.1, and C is an alkyl radical derived from the compound of formula IV: EQU R.sup.3 --Si(CH.sub.3)(OR).sub.2 (IV) and D is also an alkyl radical derived from the compound of formula V: EQU R.sup.3 --Si(OR).sub.3 (V) …
