摘　　要：通过对不同组分的改性共聚酯及其通过预结晶处理后进行DSC热分析,讨论了各类改性组分对共聚酯的玻璃化转变温度、结晶性能等方面的影响,由此推测改性组分在低熔点聚酯中所起的作用。以得到制备低熔点共聚酯的最佳配方等一些工艺参数。A series of modified PET samples and these PET samples after precrystallizing are analyzed by means of DSC. The effects of different modified compositions on the property of the co-PET, such as glass transition temperature, crystallization and so on, are discussed. So the results of these modified compositions on the low melting point polyester can be got. Some optimum processing parameters about manufacturing the low melting point polyester can also be obtained.
