Resumo |
Nonisothermal and isothermal crystallization kinetics of an aromatic thermoplastic polyimide derived from 3,3',4,4'-oxydiphthalic dianhydride and 4,4'-oxydianiline have been investigated by means of differential scanning calorimetry (DSC) and wide-angle X-ray diffraction. The results for nonisothermal crystallization study showed that a weak melting peak appeared during the first heating process, whereas no crystallization peak appeared in the DSC curve during the subsequent cooling process. On the other hand, the study for the isothermal crystallization in the temperature range of 260-330 degrees C showed that a new exothermic peak appeared at lower temperature for the samples crystallized for 100 min at 300 degrees C. |
