ABSTRACT:
A process is described for the preparation of modified polysiloxanes by reaction of polyvinylsiloxanes with compounds of the formula ##STR1## in which R is H, CH.sub.3 or C.sub.2 H.sub.5, in which at least one radical R is H, and R.sub.f is a perfluoroalkyl radical having 8 to 16 C atoms, in about equivalent amounts, relative to the vinyl groups, at elevated temperature. In addition, the polysiloxanes prepared in this manner are protected. Equally, the use of these polysiloxanes for the oil- and water-repellent treatment of fiber materials is claimed. This treatment makes it possible to achieve very good wash- and cleaning-resistant oil- and water-repellency, using small amounts of fluorine.
