    摘要: A process for preparing a thermosetting maleimide type prepolymer which comprises heating (A) a polyfunctional maleimide compound derived from a polyamine prepared from aniline and formalin, (B) a bis-maleimide and (C) a diamine. The thermosetting maleimide type prepolymer prepared according to the process of the present invention is excellent in solubility in low boiling point solvents such as acetone, methyl ethyl ketone and methyl cellosolve, which are available at low cost. Accordingly, the prepolymer is advantageously used especially for the production of laminated boards having excellent heat resisting properties.
