Abstract
The invention comprises a method for producing fluorosilicone oil by reacting a fluorosilicone trimer with a triorganosilanol in the presence of an alkali silanolate. The polymer may be condensed to increase viscosity and decrease the silanol content of the polymer, and volatiles may be removed by stripping. The method provides a high yield of fluorosilicone oil of narrow viscosity ranges in an efficient reaction, and produces small amounts of waste.
