| 摘 要： | 通过固相缩聚合成了两种不同结构的高分子量共聚酯，研究了样品的熔融行为和结晶速率。研究发现，共聚酯的熔融峰随着固相聚合温度和时间的变化而与纯ＰＥＴ有明显的差别，共聚酯泊结晶速率与慢于纯ＰＥＴ的结晶速率。

| Abstract: | The melt behaviour and crystallization rate of two kind copolyesters(additive monomer:IPA and AA)prepared by solid state polycondensation were studied. The experimental results show that the changes of melt peaks of copolyesters with changing of S. S. P.temperature and time are different from PET homopolymer. In comparision with PET,the crystallization rate of both copolyesters are also decreased. |
