| 摘 要： | 采用低温溶液缩聚的方法，合成了一种在结构上存在着大量醚键的聚酰胺，并用红外光谱(IR)、差示扫描量热法(DSC)、偏光显微镜和扫描电子显微镜（SEM）等方法进行了表征。结果表明，该聚酰胺在熔融状态下具有明显的液晶态结构，属于典型的主链型热致液晶。

| Abstract: | A novel kind of polyamide containing a great mass of ester bonds in its backbone was synthesized via a solution condensation reaction at low temperatures. The polymer was characterized by techniques such as FT IR, DSC, POM and SEM. The results demonstrate that this novel polyamide has an obvious liquid crystalline behavior when being heated into molten state, and is a typical kind of thermotropic liquid crystal. |
