| 摘 要： | 运用ＤＳＣ、结晶速度仪对ＰＥＴ／ＴＰＥＥ共混物的结晶行为进行了研究。结果表明，随着ＴＰＥＥ添加量的增加，ＰＥＴ共混物的结晶诱导期缩短，总结晶速度加快，结晶活化能减小；证明ＴＰＥＥ是ＰＥＴ良好的结晶促进剂

| Abstract: | Crystallizing behaviour of PET/TPEE polyblends was studied by JJY 1A crystallization rate equipment and DSC. Conclusions about effect of TPEE on the crystallization behaviour of PET/TPEE polyblends were drawn. TPEE can act as an excellent crystallization rate promoter, by which the crystallization rate is quickened,crystallization induction period is shortened and crystallization activation energy is decreased. |

| Keywords: | thermoplastic polyether polyester(TPEE) crystallization induction period rate constant of crystallization kinetics avrami exponent crystallization activation energy |
