Supermolecular structure of a new, wholly aromatic thermoplastic polyimide

Abstract

Abstract Polyimides are one of the important heat-resistant polymers. A large number of wholly aromatic and aromatic/aliphatic polyimides have been developed since this class of polymer was first reported in the 1960s. These polyimides are in general either not processable or processable with great difficulty. In most cases, solutions of the corresponding polyamic acid (PAA) in polar solvents are used for processing.
