Abstract

A novel class of resinous organosiloxane polymers includes triorganosiloxy, fluorinated organosiloxy, SiO.sub.4/2 and silicon-bonded hydroxyl groups. The fluorine-containing hydrocarbon radicals are bonded to silicon by means of a sequence of at least two methylene group. Preferred organosiloxane polymers stabilize the cellular structure of polydimethylsiloxane foams during curing.
