Abstract
Described are polysiloxane compositions that are obtainable in 2 steps. The first step comprises reacting a linear organopolysiloxane which contains Si—H bonds with a compound that has a terminal C═C double bond and a polyoxyalkylene chain. This reaction is carried out in such a way that Si—H bonds are still present in the resultant product. The second step comprises adding a base or water and an acid to the resultant product. The hydrophilic properties of the resultant polysiloxane compositions can be influenced in a specific manner. The compositions are useful for treating fiber materials, especially textile fabrics. The effects obtained are notable for good durability. Further groups may be incorporated into the polysiloxanes to open up further applications.
