    Abstract: This invention provides thermosetting-resin-forming compositions which are formed of (a) a bismaleimide compound represented by the following formula: wherein R represents a divalent group of or X being a direct bond or a group selected from divalent hydrocarbon groups having 1-10 carbon atoms, hexa-fluorinated isopropylidene, carbonyl, thio, sulfinyl, sulfonyl and oxo, and (b) a specific diallylbisphenol compound. These compositions can provide thermosetting resins having high cracking resistance due to improved impact resistance and toughness and low water absorption.

    Abstract: A thermosetting resin composition formed of a polyaminobismaleimide resin, which is prepared from a bismaleimide compound and a diamine compound, and a powdery inorganic filler. The composition has excellent heat resistance as well as superb mechanical properties at high temperature not to mention room temperature, and is expected to find wide-spread commercial utility in electric and electronic components, e.g., as a sealing material in sockets and connectors and for other applications.

    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.
