Abstract

PURPOSE: To obtain the title compound useful as a raw material for high-quality thermosetting resins usable for varnishes, powder coatings, laminates, and molded articles, in high yield and purity, by reacting a bis- or poly-maleimide with a diene compound.
CONSTITUTION: A bismaleimide, e.g. N,N'-(4,4'-diphenylmethane)bismaleimide, of formula I: {Z is formula II [D is CH2, SO2, O, C(CH3)2, or S;R1 is H or 1W4C alkyl group], or formula III (R2 is H or CH3)} or a poly(phenylmethylene) polymaleimide of formula IV: [l, m, and n are integers ≥0; the average value of (l+m+n) is 0.1W5] is reacted with a diene compound, e.g. isoprene, in the presence of an organic solvent, preferably at 0W150°C, to give a bis- or polyimide. The compound of formula I or II can be obtained by cyclization of the corresponding amine with maleic anhydride through dehydration.
