METHOD FOR PRODUCING SOLVENT-SOLUBLE POLYIMIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a solvent-soluble polyimide, advantageous in production equipment and productivity. SOLUTION: The method for producing the solvent-soluble polyimide comprises polycondensing one or more kinds selected from a specific aliphatic tetracarboxylic dianhydride, an aliphatic tetracarboxylic acid and a derivative of the aliphatic tetracarboxylic acid, with one or more kinds of diamine compounds in the presence of a tertiary amine compound in a solvent.
