摘要
分析了在聚酯切片固相缩聚中,切片粘连的原因,介绍了有效控制粘连现象发生的经验,包括合理的升温控制、氮气流量、反应温度等。
The reasons of PET chips co nglutination during the solid-phase polycondensation are ana-lyzed,and then our experiences in pr eventing chips from conglutination are introduced,which in-clude the conrol of temperature rising,flow of N 2 ,temperature of reaction and so on.
