摘要
利用介晶基和非个晶基共聚的方法合成高分子液晶，详尽介绍了合成方法和对产品的测试表征，并介绍了所合成的聚合物要呈现液晶态，允许非介晶组分在其组成中所占的最高含量。
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.
