| 摘 要： | 用个晶基和柔性更好的非个晶基共聚的方法合成高分子液晶，通过热台偏光显微镜、ＤＳＣ和Ｘ－光衍射仪对所合成的共聚物进行了结构和相态表征，讨论了共聚物组成对共聚物相变温度和相态的影响，确定了共聚物要呈现液晶态，允许非介晶组份在其组成中的最高含量。

| Abstract: | A series of main chain liquid crystalline coPOlymers is reported. Themesomorphous properties are examined by visual observation of optical POlarizing microscope,DSC and X-ray difftaction. It was found that all thermotropic liquid crystalline copolymers arenematic mesophase,and that copolymeritalion depresses crystallization transition temperatures andliquid crystalline transitions are weight-averaged over those of the parent homopolymers. Themaximum mole fractions of non-mesogenic units needed for apperance of melt anisotropy areabtained. |
