摘要
以4.4′-二羟基氧化偶氮苯和1,10-癸二醇作为含羟基单体,按不同的重量配比,合成了一系列含氧化偶氮苯液晶基元的共聚液晶高分子,改变液晶基元的含量,共聚物相变温度可以调节。
A series of liquid crystalline copolymers with azoxybenzene mesogens were synthesized from 4. 4' -dihydroazoxybenzene and 1,10-decamethylene glycol with different weight ratio by the solution polycondensation with an diacid dichloride. By changing the mesogen content in the copolymer molecules, the phase transformation temperature of the copolymers could be regulated while their liquid crystalline properties were not sacrificed in the range of the selected monomer ratio.
