ABSTRACT:
Liquid diorganovinylsiloxy terminated polydiorganosiloxanes wherein at least 50 percent of the hydrocarbon radicals bonded to silicon contain at least one perfluorinated carbon atom are prepared by polymerizing the corresponding diorganocyclosiloxane(s) at a temperature of from 25.degree. to 150.degree. C. under superatmospheric pressure and in the presence of a controlled amount of water and a catalytically effective amount of ammonia. The resultant silanol terminated polydiorganosiloxane is reacted with a hexaorganodisilazane containing a vinyl radical bonded to each of the two silicon atoms.
