Abstract

The present invention is a method for the preparation of carbinol-functional organosiloxanes and carbinol-functional organosiloxane resins. The method comprises contacting a cyclic silyl ether with an organosiloxane or an organosiloxane resin at a temperature within a range of about 25.degree. C. to 150.degree. C. The method may be conducted in the presence of an inert organic solvent to facilitate dissolution and contact of the reactants.
