Abstract
Novel rubber-modified rigid silicone resins are disclosed. The novel 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. The novel rubber-modified rigid silicone resins of the invention show remarkably high fracture toughness, K.sub.Ic, and critical strain energy release rate G.sub.Ic.
