ABSTRACT:
Silicone resins containing monorganosiloxane and diorganosiloxane units and exhibiting reproducible values of molecular weight and dispersity are prepared by condensing a mixture of hydrolyzed silanes, adjusting the solids content of the condensed resin and then subjecting the resultant product to a re-equilibration reaction in the presence of an alkali metal compound.
