A semiconductor encapsulating material is obtained from a polyimide resin composition comprising (A) a polyaminobismaleimide resin, (B) a silicone monomer and/or oligomer having a hydroxyl or alkoxyl group bonded to a silicon atom and mixtures thereof, and (C) an inorganic filler wherein the weight ratio of polyaminobismaleimide resin (A) to silicone component (B) ranges from 99.5/0.5 to 70/30, and the weight ratio of polyaminobismaleimide resin (A) to inorganic filler (C) ranges from 100/50 to 100/1000.
Disclosed are a reaction mixture for preparing a polyfunctional maleimide-based thermosettable resin composition comprising a bismaleimide or a polymaleimide and an ether derivative of an alkenylphenol; the polyfunctional maleimide-based thermosettable resins comprising the reaction product of the reaction mixture; a process for the manufacture of the resins; and their use in a prepreg containing carbon, boron. glass or other fibers.
Novel thermoset polymers are prepared by reacting an allyl or vinyl aryl or aryloxy substituted cyclophosphazene with a bis-maleimide.
