New semi-interpenetrating (semi-IPN) polymeric networks from commercial polysulfone (UDEL RP-1700) and thermosetting bismaleimide (4, 4'-bismaleimidodiphenylmethane) (BMDM) and maleimide terminated polyaminobismaleimide prepolymer based upon BMDM and 4, 4'-diaminodiphenylmethane were prepared. The chemistry, processing, physical and mechanical properties, phase morphology, thermal stability and solvent resistance of the neat resins are presented. The interrelationships among structure, processing, propcrties, and morphology are also discussed.
