| 摘 要： | 本文用乙氧基做为主链与侧链的柔性间隔，合成了手性侧链液晶高分子．通过ＤＳＣ，热台偏光显微镜及Ｘ－衍射等手段，研究了柔性间隔链长对液晶行为的影响．结果表明，这类液晶高分子有较宽的相变温度范围．聚合物的相变温度及液晶态的形成与柔性间隔链长有关．

| Abstract: | A new series of polymethacrylates with a chiral mesogenic pandant group linked to backbone through ethyleneoxide units of different lengths were synthesized. Mesomorphic behaviour of polymers was characterized by polariaing microscopy with hot stage, DSC and X- ray diffraction The results show that phase transition temperature and isotropic temperature depended on the length of ethyleneoxide. |
