| 摘 要： | 主要通过 DSC 对钛催化剂合成 PET 聚酯的预结晶性能进行了研究，以探索钛催化剂对聚酯预结晶性能的影响，并将其与锑系聚酯进行对比。结果表明，相比较锑系聚酯，钛催化剂合成 PET 聚酯切片内部残留结晶度低，冷结晶速度慢，同样工艺条件下钛系聚酯预结晶过程更容易粘结。

| Abstract: | The pre-crystallization properties of PET synthesized with Ti-based catalyst was investigated using differential scanning calorimetry （DSC）.And the studied results was compared with the Sb-based catalyst synthe-sized PET polyesters.Results indicate that the PET polyester chips which synthesized with Ti-based catalyst have low degree of residual crystallinity and slower cold crystallization speed.And the Ti-based chips also easier to bond-ing under the same process condition compared with the Sb-based chips. |
