ABSTRACT:
A method for producing triorganosilyl-end stopped diorganopolysiloxane fluids having a viscosity varying from 50 to 2,000,000 centipoise at 25.degree. C. comprising reacting a silanol end-stopped fluoro substituted polymer with a halogenated silane in the absence of base such that the silanol groups at the ends of the polymer are substituted by triorganosilyl groups. The advantage of the above process is that a high yield of the desired fluid is obtained.
