| 摘 要： | 分子结构与液晶行为间的关系是液晶性高分子物理问题研究的核心，通常的液晶性高分子中除液晶性基元外还引入一些相对来说很柔顺的链段，称作柔性间隔段．这是因为人们认识到高分子的液晶行为不只决定于液晶性基元的结构，也受到这些基元间以及基元和间隔段间相互作用的影...

| Abstract: | A series of polyesters based on triad aromatic ester mesogenic unit but different length of poly(ethylene oxide) flexible spacers in the main chain was prepared by solution polycondensation and its chemical structure and mesogenic behavior were examined.The intermediates of each step and assynthesized polymers and monomers containing mesogenic unit were characterized by elementary analysis,IR, 1H NMR and melting point measurement. |
