  • Chloride reduction in polysiloxanes
    Patent number: 4962221
    Abstract: The instant invention is a process for reducing residual chloride content of polysiloxane fluids, without detrimental effects on the polysiloxane polymer. The process comprises contacting the polysiloxane fluid, containing residual chloride, with selected weakly-basic alkaline metal compounds at a temperature less than 100.degree. C. After an appropriate contact time, the polysiloxane fluid is separated from the solid alkaline metal compounds. In a preferred embodiment of the present invention, water is added to the process to facilitate removal of residual chloride.
