The results showed that nematic liquid crystalline mesophase was obtained when the temperature decreased, and was confirmed by the second endotherm corresponding clearing temperature of DSC curve as well as SAXD, WAXD curves.

- 聚合物在偏光显微镜下观察到降温过程中能够形成向列型的介晶态,并在DSC曲线上出现清亮点转变峰,另外由X光衍射图谱得知聚合物不存在长程有序结构,仅存在分子的近程有序,属典型的向列型热致性液晶聚酰胺。
