| 摘 要： | 采用低温溶液聚合方法，以Ｎ－（２，５－二羟基苯）亚甲基－４－取代苯胺和不同结构的二酰氯为单体，合成了两类新的高分子．聚合物的液晶行为用ＤＳＣ、偏光显微镜和Ｘ射线衍射进行了表征，发现其中一类为向列型热致液晶高分子，另一类则无液晶性．随单体结构的改变，聚合物的特性粘数、熔点（Ｔｍ）和液晶态的清亮点（Ｔｉ）均呈现规律性变化。

| Abstract: | Two new kinds of polymers were synthesized by low temperature solution polycondensation by using N-2,5-dihydroxy benzylidene-4-substitued aniline and diacid chloride with different structures as the monomer. The liquid-crystalline behavior of the polymers was characterized by DSC,polarizing microscopy with a heatlng stage and X-ray diffractometer.It was found that one kind of the polymers was nematic thermotropic liquid crystal polymers,and the other kind of polymers was non-liquid-crystalline. The intrinsic viscosities,Tm and Ti of the polymers changed regularly with the change of the structure of the monomers. |
