| abstract |
Thermosetting resin compositions are provided which comprise aromatic bismaleimide derivatives, for example, 2,2-bis[4(3-maleimidephenoxy)phenyl]propane and diamine derivatives, for example, 4,4'-bis(3-aminophenoxy)biphenyl. Prepolymers are also prepared by conducting heat-treatment of said compositions. The compositions of this invention are used for thermoforming such as compression molding etc. as well as raw materials of adhesives and coatings. The compositions provide molded articles which are excellent, for example, in impact strength, flexibility and high-temperature stability. |
