ABSTRACT:
An addition type imide resin prepolymer is obtained by a reaction of unsaturated bisimide of 1.0 mol to diamine of 0.25 to 0.43 mol and an addition of polyamine having three or more benzene rings. The prepolymer is thereby made to contain substantially no unreacted diamine component which affects human body of operators, and to have remarkably excellent heat resistance and adhesive properties, while effective to restrain a production of any component of a molecular weight exceeding 15,000.
