%X The mechanism of crystallization and liquid crystallization of an aromatic thermotropic polymer-thermotropic poly (octamethylene p, p'-bibenzoate) were investigated detailedly with DSC and hot-polarized microscope and the surface fre energy and temperature coefficient of these phase transitions were determined and estimated. The results suggest that liquid crystallization process of the polymer is heterogeneous in two-dimentional nucleation and linear growth in twodimensional with a value of Avrami exponent n to be 2.7,while the crystallization process is heterogeneous in two-dimentional nucleation and linear growth in three dimensional with a value of n to be 4.2-4.5.From the analysis of surface free energy and temperature coefficient of liquid crystallization and crystallization processes, it is found that liquid crystallization process is much faster than the crystallization process, and the liquid crystallization is more temperature sensitive than the crystallization.
