Abstract
The present invention relates to methods for making silicone resins. More particularly, the present invention relates to methods for producing silicone resins comprising monofunctional units in the form of R.sub.3 SiO.sub.1/2 units and tetrafunctional units in the form of SiO.sub.4/2 units. The methods of the present invention are characterized by a continuous process for producing silicone resins while maintaining a constant ratio of reactants thus producing less variation in the final product. The present invention is further related to the compositions produced by the methods of this invention.
