Abstract
PURPOSE:To obtain the title film having improved heat resistance and mechanical strength by forming a liquid thin film of a resin composition prepared from an aromatic polyimide resin dissolved into a halogenated phenol compounds and then evaporating to remove the solvent from the liquid film. CONSTITUTION:An aromatic polyimide resin having more than 90% of repeating unit as polymer main chain of the formula I (R1 is a radical removed amino group from aromatic diamine of the general formula H2N-R1-NH2) is dissolved into molten halogenated phenol of formula II or III (R2 are H, C1-3 alkyl; X is halogen) having less than 100 deg.C of melting point and less than 300 deg.C of boiling point to prepare a polyimide resin composition and forming a liquid thin film from the polyimide resin composition, then after, evaporating to remove the halogenated phenol from the liquid film at 50-300 deg.C under normal or reduced pressure, thereby the title polyimide film is obtained.
