| 摘 要： | 研究PET固相缩聚的工艺流程,分析PET切片的前期预处理对整个固相缩聚的影响,发现PET切片在结晶前进行干燥处理有利于固相缩聚工艺.当PET切片充分干燥后.再结晶处理,可缩短整个固相缩聚反应时间,从而提高产量和效益.

| Abstract: | It has been studied for the technology process of solid-state polymerization(SSP) of PET.It is found that it is beneficial for technology of SSP,when the PET polymer particles are dried before crystallization.If the PET polymer particles are dried fully,it is possible that the reaction time of SSP is reduced. |
