摘　　要：本文采用热分析法(DSC)测定了PET 等温冷结晶过程和PET、ECDP 熔体结晶过程的结晶速率和Avrami 参数。探讨了PET 分子改性后结晶行为的变化。在相同等温熔体结晶温度下,ECDP 的结晶速率比PET 低。熔体骤冷样品升温结晶峰温度ECDP 比PET 低4.5℃左右。The crystallization rate and Avrami index were determined by mcan of DSC in this paper, when PET underwent cooling crystallization,and ECPD melts isothermal crystallization,The crystallization behavoir of modified PET was explored,under the Same temperature,the crysta- llization rate of ECDP melts was lowcr than that of PET.The temperature of cooling cry- stallization peak of ECDP was lower about 4.5℃ than that of PET.
