摘要
用分子结构参数计算了一类含有液晶聚酯和聚乙二醇的嵌段共聚物的无扰尺寸和扩展因子 ,进而应用Meier的微相分离理论对该类液晶嵌段共聚物的微区尺寸进行了理论计算 ,并用透射电镜测试了该液晶嵌段共聚物的微区尺寸 ,实验结果与理论计算值相符 .
The unperturbed dimension and extension factor of a block copolymer comprise of liquid crystalline polyester and poly(ethylene glycol) were calculated by molecular structure parameter, then the domanin size of liquid crystalline block copolymer was calculated by Meier's microphase separation theory ,and the domain size of liquid crystalline block copolymer was tested by transmission electron microscopy(TEM), the experiment result agrees with the value calculated from the theory.
