摘要： 用1,10-癸二醇、聚四氢呋喃二醇(分子量为1050)与含液晶基元的缩聚单体2-甲基对苯撑双(4-氯甲酰)苯甲酸酯,通过溶液缩聚反应合成了一系列序列嵌段共聚酯。当聚四氢呋喃二醇与癸二醇的重量配比小于70/30时,共聚物具有明显的液晶性。共聚物的液晶性用偏光显微镜、DSC和X射线衍射进行了表征。

Abstract: Aseries of sequential block copol'ymers was synthesized by polycon-densation of 1,10-decanediol, poly(oxytetramethylene)glycol (MW=1050) and the mesogenic monomer 2-methyl-p-phenylene di(4-chloroformyl)benzoate. These polymers were found to be liquid crystalline when the feed ratio of poly(oxytetramethylene)glycol to 1,10-decanediol was less than 70 to 30. The mesomorphic behavior of these polymers was characterized by a polarizing microscope, a DSCinstrument and a X-ray diffractometer.
