Abstract

PURPOSE:To readily produce a polyimide having excellent film moldability and film forming properties, by reacting a bismaleimide with a diamine in the presence of an acid catalyst in cresol. CONSTITUTION:A bismaleimide expressed by formula I (R is formula II or III; A is methyl, ethyl, methoxy or chloro; B is H or same as A) is reacted with a diamine expressed by formula IV (Y is -O- or -CH2-; C and D are H, methyl or ethyl) in the presence of an acid catalyst in cresol solvent at 50-65 deg.C.
