摘　　要：采用界面缩聚的方法,以异山梨醇为刚性基元、柔性基元癸二酰氯、离子基元灿烂黄为主要原料,合成了热致性主链液晶离聚物。通过傅立叶转换红外光谱(FT-IR))对其结构进行了表征,采用偏光显微镜(POM)、示差扫描量热仪(DSC)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型热致液晶,随着离子基元的加入及含量的变化对液晶性和液晶类型都没有影响。Thermotropic main-chain liquid crystalline ionomers were synthesized from isosorbide,sebacoyl chloride and brilliant yellow by interfacial condensation reaction.The structure of polymers was characterized by infrared spectroscopy(FT-IR),the liquid crystal properties were characterized by POM,DSC and X-ray.The results show that the ionomers are monotropic smectic A thermotropic mesophase;the mesophase properties and the type of polymers are not affected by the addition of ion element brilliant yellow.
