SILICONE-POLYIMIDE COPOLYMERS CONDENSATION VULCANIZABLE COMPOSITIONS OBTAINED THEREFROM, AND METHODS FOR MAKING ABSTRACT OF THE DISCLOSURE Silicone-polyimide copolymers having terminal silanol or silicon hydride radicals are provided based on the use of a norbornene terminated polyimide. A hydrosilation reaction is employed to introduce silicon-hydrogen into the terminal position of the polyimide having norbornene termination. The resulting hydrosilyl terminated polyimide is reacted with silanol terminated polydiorganosilane in the presence of a catalyst to produce silanol terminated polydiorganosiloxane-polyimide copolymer. Room temperature or low temperature condensation vulcanizable compositions based on the use of such silanol-terminated copolymers provide cured silicone-polyimide copolymers exhibiting improved toughness.
