摘要
利用介晶基因和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，并研究了非介晶基因对液晶共聚醚相变温度的影响，及液晶聚合物相变温度与其组成之间的关系。
A series of main Chain Liquid Cryslattine copolymers is reported. The copolymers were synthesed from were examined by visual observation of optical polarizing microscope. DSC and X - ray diffraction. It was found that all the thermotropic liquid Crystalline copopymers were nematic mesophase. Copolymerization depresses Crystallization transition temperatures and Liquid Crystalline transition were weight-averaged over those of the parent homopolymers. The maximum wole fractions of non-mesogenic units needed for apperance of melt auisotropy were obtained.
