摘要

The biphasic behavior and phase transitions of a thermotropic main-chain liquid crystalline polyester, the poly (oxytrimetilen-etilen glycol p, p′-bibenzoate), was studied by X-ray diffractometry, differential scanning calorimetry (DSC), and rotational rheometry. The liquid crystalline mesophase structure of the polymer evolves from Smectic C to Smectic A at around 100° C and changes to the isotropic state at about 200° C. The annealing of ...
