ABSTRACT:
A method for preparing an aminoalkoxysiloxane comprises reacting a siloxane having at least one Si--X bond with an aminoalcohol of the general formula HO--R--NR.sup.1.sub.2 and removing HX from the reaction mixture, wherein X is a hydrogen atom, an --OH group or an --OC(O)NR.sup.1.sub.2 group, R is a divalent substituted or unsubstituted alkylene or arylene group, and R.sup.1 is a hydrogen atom or an alkyl group having from one to eighteen carbon atoms. The siloxane and aminoalcohol are preferably HO(Me.sub.2 SiO).sub.4.5 H and ethanolamine, (Me.sub.3 SiO).sub.2 MeSiH and ethanolamine, isopropanolamine or 3-aminopropan-1-ol, or Me.sub.3 SiO(Me.sub.2 SiO).sub.3 (MeHSiO).sub.5 SiMe.sub.3 and isopropanolamine respectively. The aminoalkoxysiloxanes thus prepared are useful for treating textile fabrics.
