摘　　要：The compatibilizer (TLCP-b-PC) of 60PHB/PET thermotropic liquid crystal polymer (TLCP) and polycarbonate (PC) blend system was prepared. The synthesis and characterization of the compatibilizer as well as its effects on the microscopic morphology and the mechanical properties of the TLCP/PC blend system were studied with a series of analysis ways, such as Soxhlet extraction, infrared absorption spectroscopy,electron microscopy, etc. It is shown that the ideal reaction condition for preparing the compatibilizer is:the reaction temperature of 275℃, the reaction time of 20minutes and without catalyst. And the compatibilizer can improve the compatibility of the blending system of 60PHB/PET and PC.The compatibilizer ( TLCP-b-PC ) of 60PHB/PET thermotropic liquid crystal polymer ( TLCP) and polycarbonate (PC) blend system was prepared.
