ABSTRACT:
Novel rubber-modified rigid silicone resins a novel method of making the same are disclosed. The resins are the copolymerized reaction product of (A) an organosilicon composition selected from the group consisting (I) an organosilicone resin, (II) hydrolyzable precursors of (I), and an hydrolyzate of (II) and (B) an silicone rubber. In the method of the invention, the copolymerization step is carried out in an organic solvent, preferably utilizing a relatively weak condensation catalyst. Thereafter, the solution is devolatilized and the composition cured by heating.
