LINEAR POLYIMIDE PRECURSOR, LINEAR POLYIMIDE, THERMALLY CURED PRODUCT OF THE LINEAR POLYIMIDE, AND METHOD FOR PRODUCING THE LINEAR POLYIMIDE

Document Type and Number:

WIPO Patent Application WO/2009/145339

Kind Code:

A1

Abstract:

Disclosed is a linear polyimide obtained from mellophanic acid dianhydride, a diamine (NH2-A-NH2) and a monofunctional acid anhydride and containing a repeating unit represented by general formula (3) (wherein A represents a divalent aromatic diamine residue or an aliphatic diamine residue, B represents a monofunctional acid anhydride residue, and n represents the polymerization degree). The polyimide has excellent solubility in organic solvents and thermoplasticity, while exhibiting high adhesion to copper foils or non-thermoplastic polyimide films, high glass transition temperature and high toughness.
