Abstract

Organopolysiloxanes in which two polysiloxane chains are bonded via a divalent radical can be obtained by reaction of cyanuric halides with organopolysiloxanes which contain primary amino groups in substituents. The divalent radical contains 1,3,5-triazine rings, to which a halogen atom is still bonded. The organopolysiloxanes thus obtained are suitable for soft handle treatment of fiber materials. In particular, textile sheet-like structures which comprise cellulose fibers can thereby be given a soft handle and improved permanence of the treatment effects with respect to washing processes.
