| 摘 要： | 热致性液晶共聚酯ＰＥＴ／６０ＰＨＢ组分对ＰＥＴ及ＰＢＴ在两种共混体系中的非等温结晶行为的影响用ＤＳＣ方法进行了研究，并用Ｏｚａｗａ方法处理了动力学数据。随共混体系ＬＣＰ含量的增加，ＰＥＴ的Ａｖｒａｍｉ指数ｎ趋于降低而ＰＢＴ的ｎ值趋于增加，表明在非等温结晶条件下，对不同组成的共混物体系有着不同的成核和晶体生长的机理。

| Abstract: | The effect of the thermotropic copolyester of PET/60 PHB on the non isothermal crystallization behavior of both the PET and PBT in the blends has been studied by DSC method. The kinetic data was treated by Ozawa approach. With increasing the content of LCP in the blends the values of Avrami exponent n decrease for PET whereas increase for PBT, implying a different mechanism of nucleation and growth of crystal occured during the non isothermal crystallization conditions. |
