Abstract: 1. A thermosetting resin composition which comprises a bismaleimide derivative having the formula (I): and a diamine derivative having the formula (II): wherein R is a divalent radical represented by or where X is selected from a bond, a divalent hydrocarbon radical having 2 carbon atoms, hexafluorinated isopropylidene radical, carbonyl radical, thio radical and sulfinyl radical. A thermosetting resin prepolymer may be obtained by conducting heat-treatment of the thermosetting resin composition at a temperature of 70 to 220 DEG C in the presence or absence of a solvent.
