Abstract

PURPOSE:To obtain the title compound which can give a polyimide having various performances, by imidating a polyamic acid obtained from a specified diamine component and a tetracarboxylic anhydride in an organic solvent azeotropically distillable with water. CONSTITUTION:A polyamic acid solution is obtained by reacting a diamine component (A) comprising a hydroxy diamine (A) of formula I (wherein Y is a bivalent organic group) and, optionally, other aromatic and aliphatic diamine with 0.9-1.1mol, per mol of component A, of tetracarboxylic anhydride (B) in an organic solvent. An organic solvent (e.g., xylene) azeotropically distillable with water is added to this polyamic acid solution, and the mixture is imidated by heating to about 180 deg.C while the formed water is distilled out of the system to obtain the title compound having structural units of formula II (wherein X is a tetravalent organic group) as repeating units.
