Abstract:
A method of neutralizing a polysiloxane having acidic residuals is disclosed. The method involves contacting a polysiloxane having acidic residuals with a carbon solid, and separating the carbon solid from the polysiloxane. This invention is particularly useful to neutralize residual acid polymerization catalysts in organopolysiloxanes.
