| 摘 要： | 以低温溶液缩聚方法,合成了一系列主链上具有X-型液晶基元的液晶高分子。所有聚合物样品均具有明显的热致液晶性。不同柔性链段长度和取代基对聚合物的液晶性呈规律性的影响。并用IR、H-NMR、WAXD和热台偏光显微镜等方法对聚合物进行了表征。

| Abstract: | A series of the main chain liquid crystal polymers with X-shaped mesogens were synthesi-ed by low temperature solution polycondensation. All polymer samples had obvious thermotropic properties. Both flexible spacers and substituents had influence on the liquid-crystalline behaviour of the polymers The polymers were characterized by IR spectrometer, H-NMR spectro-scopy, DSC, polarizing microscopy and X-ray diffractometre. |
