甲亚胺液晶共聚醚的合成及研究（Ⅱ）

SYNTHESES AND STUDY(Ⅱ) OF AZOMETHINE LIQUID CRYSTALINE COPOLYETHER

利用刚性较强的介晶基团与较柔软的非介晶基团共聚的方法合成了一系列具有较低相变温度的向列型液晶高分子─甲亚胺液晶共聚醚，并利用热台偏光显微镜、差示扫描量热计（ＤＳＣ），Ｘ─光衍射对其相变温度和液晶态进行了测定和表征，研究了非介晶基团对液晶共聚醚相变温度、液晶态的影响，以及液晶聚合物的相变温度与其共聚组成之间的关系。

series of nematic liquid crystalline polymer azomethine liquid crystalline copolyether of lower phase transition temperature are synthesised with mesomorphic radical of strong rigidity and soft non-mesomorphic radical.It's properties of phase transition temperature and liquid crystalline phase are investigated by thermal platform polarizing microscope,differential scanning calorlmetry(DSC)and X-ray diffiration.The influences of non-mesomorphic radical on its phase transition temperature and crystaline phase are discussed,the relation between its phase transition temperature and compositions of copolymerization are discussed as well.
