Abstract

PURPOSE: Tetracarboxylic acid component and aromatic diamine component at a specified molar ratio are polymerized in a solvent of halogenated phenol at a specific temperature followed by imidization to produce title solution suitably used as a varnish for coating electric wires that gives cured films with high strength.
CONSTITUTION: The polymerization of (A) tetracarboxylic acid component containing more than 80mol% of 3,3',4,4'-biphenyltetracarboxylic acid and (B) aromatic diamine component containing more than 70% of 4,4'-diaminodiphenylether at a sustantially equimolar ratio is effected in a solvent of halogenated phenol as p-chlorophenol, etc., at about 100W300°C, followed by imidization to produce the objective solution of polymer with the structure given in the formula as the major component.
