利用等温和非等温方法详细研究了芳香族聚酯──热致型聚合物对，对’－联苯二甲酸二辛酯的结晶相和液晶相形成机理，并计算了相变过程中的表面自由能与温度系数，研究结果表明：从介晶相开始的结晶过程是二维异相成核、三维线性增长的，而从各向同性液相开始的液晶相形成过程则是二维异相成核二维线性增长的．对两个晶化过程的表面自由能的研究表明，该聚合物液晶相形成过程的相转变表面自由能比结晶过程小得多，预示了它将具有更大的晶化速率．研究还发现，该聚合物的液晶相形成过程具有比结晶过程大得多的温度敏感性．
The isothermal and non-isothermal method was used to study the formation mechanism of the aromatic polyester-thermotropic polymer, the crystal phase and the liquid crystal phase of dioctyl phthalate, and the surface phase Free energy and temperature coefficient, the results show that: the crystallization process from the mesophase is two-dimensional heterogeneous nucleation, three-dimensional linear growth, while the liquid crystal phase from the isotropic liquid phase formation process is two-dimensional heterogeneous Two-dimensional nucleation of linear growth. The study of the surface free energy of the two crystallization processes shows that the phase transition surface free energy of the polymer during the formation of the liquid phase is much smaller than that of the crystallization process, indicating that it will have a greater crystallization rate. The study also found that the polymer’s liquid crystal phase formation process has a much greater temperature sensitivity than the crystallization process.
