Abstract

A novel aromatic dianhydride monomer, 3,3′-oxybis[(3,4-dicarboxyphenoxy)phenol] dianhydride, was successfully synthesized in three steps using 3,3′-oxybis(phenol) as starting material, which was reacted with 4,4′-oxydianiline (ODA) via a conventional thermal or chemical imidization method to produce a new polyimide. The resulting polyimide exhibited excellent solubility, and film-forming capability.
