PET固相缩聚反应速率的影响因素

摘要

The simple technological process of soild-state polycondensation reaction was described.The effect of raw material chip,reaction temperature,crystallinity,nitrogen,residence time on solid-state polycondensation reaction was analysed.The corresponding optimal control standards were concluded.%介绍了PET固相缩聚反应的简单工艺过程,分析了原料切片、反应温度、结晶度、氮气、停留时间等对固相缩聚反应的影响,总结出相应的最佳工艺控制标准.
