Abstract

PURPOSE: To prepare a heat-resistant resin, polybenzopyrrolone, with excellent solubility in various solvents, by the reaction of a bisbenzofuranone derivative with an amine.
CONSTITUTION: (A) A bisbenzofuranone derivative of formula II [Wherein A is (substituted) aromatic ring] [e.g., 5,5'-bis(3-benzylidene-3H-benzofuran-2-one0], obtained by the condensation of a tetracarboxylic acid dianhydride of formula I (wherein X is a bond or divalent substituent) and a phenyl acetate, and (B) a diamine (e.g., 4,4'-diamino-diphenylmethane), in an approximately equal mol ratio, are condensed in an organic solvent (e.g., N-methyl-2-pyrrolidone) at about 200W 280°C for about 1W100hr, to prepare a polybenzopyrrolone of formula III (wherein R is a divalent substituent; n is 3W200).
