摘要
采用界面缩聚的方法,以联苯二酚、异山梨醇和癸二酰氯为主要原料,合成了含磺酸基热致性主链液晶离聚物。利用红外光谱分析(IR)对其结构进行了表征,采用偏光显微镜(POM)、和广角X射线(X-ray)等手段对其液晶性能进行了表征。结果表明:该离聚物为近晶A型液晶。
Thermotropic main chain liquid crystalline ionomer containing sulfornate was synthesized from 4,4＇-biphenol,isosorbide and sebacoyl chloride by interfacial polycondencation.Structures of the ionomer were characterized by Infrared spectroscopy（FT-IR） and the liquid crystal properties were characterized by POM,DSC and X-ray.The results show that the ionomer is smectic A liquid crystal.
