摘要：

Semicrystalline LaRC-TPI (Langely Research Center-Thermoplastic Polyimide) is known to be capable of recrystallizing to higher melting crystalline forms upon initial melting. The behavior of these different crystalline forms has not been studied before. This study uses techniques of differential scanning calorimetry and X-ray diffractometry to investigate these crystalline structural changes during recrystallization of this material. Semicrystalline LaRC-TPIs synthesized form three different laboratories are included in this work.
