Abstract: The diamine compound of formula(I) is produced by acylation reacting an aromatic acid ester of formula(II) in the organic solvent to obtain an acyl chloride compound, reacting the acyl chloride compound with a diamine of NH2-R1-NH2 or a nitroamine of NH2-R1-NO2, and hydrogenation reacting the reactant. In the formulas, R1 and R2 are each monocyclic aromatic gp. or non-condensation multicyclic aromatic gp. The polyimide copolymer having a good heat resistance is produced by reacting the diamine compound of formula(I) with an aromatic organic dianhydride in the organic solvent i. e. N, N-dimethyl acetamide, N, N-dimethyl formamide and/or N-methyl-2-pyrrolidone, and cyclization reacting the produced polyamide acid ester.
