• The Aurum thermoplastic polyimide, derived from pyromellitic anhydride and 4,4'-bis(3-aminophenoxy)biphenyl, has been claimed as a crystalline polyimide with excellent heat resistance and injection moldability, and can be used to produce high-performance parts. Various properties and the crystalline properties of the Aurum thermoplastic polyimide have been characterized to some extent in the literature. The temperature resistance of Aurum is significantly dependent on its crystallinity. Although Aurum is crystalline, it often solidifies in an amorphous form in a practical processing cycle. Thus, an annealing procedure at high temperature is often necessary for the Aurum to develop enough crystallinity if higher temperature resistance is required. Of course, the annealing procedure increases the manufacturing cost. If the crystallization behavior of Aurum is sufficiently understood, it will be. helpful for the determination of the molding condition or annealing condition, and may lower the cost. However, systematic studies on the crystallization of Aurum from a practical viewpoint have been scarce. In this study, the
