摘要
用特性粘度（［η］）和羧值为参数，研究了双唑啉化合物（ＢＯＺ）对聚对苯二甲酸乙二酯（ＰＥＴ）的扩链反应动力学过程，表明ＢＯＺ是与ＰＥＴ中羧基反应，考察了不同工艺生产的ＰＥＴ的扩链效果。
The coupling reaction kinetics of BOZ on the Poly (ethylene terephthalate)(PET) have been studied by intrinsic viscosity( ) and carboxy value( CV ).The experimental results show that the reaction occurrs between the BOZ and the carboxy group of PET.Effect of chain extension on the PET produced by different technology and factory have been investigated.These results show that the accessihle maximum of products depend on /CV of PET samples.
