POLYIMIDE PRECURSOR COMPOSITION, METHOD FOR PREPARING POLYIMIDE PRECURSOR, POLYIMIDE MOLDED ARTICLE, AND METHOD FOR PREPARING POLYIMIDE MOLDED ARTICLE

摘要

A polyimide precursor composition includes a polyimide precursor including a condensation polymer of a tetracarboxylic dianhydride containing a first tetracarboxylic dianhydride having a benzene ring to which two carboxylic anhydride groups are bonded, and a second tetracarboxylic dianhydride other than the first tetracarboxylic dianhydride, and a diamine compound; and a first aqueous solvent containing water and at least one water-soluble organic solvent selected from the group consisting of a water-soluble ether solvent, a water-soluble ketone solvent, and a water-soluble alcohol solvent, or a second aqueous solvent containing a water-soluble alcohol solvent and at least one water-soluble organic solvent selected from the group consisting of a water-soluble ether solvent and a water-soluble ketone solvent, wherein the polyimide precursor is dissolved in the first aqueous solvent or the second aqueous solvent.
