Molecular Weight and Its Distribution of PET Depolymerization Catalyzed by Zn(Ac)2 under Microwave Irradiation

摘要：

　　In this paper,the molecular weight and its distribution of PET during the process of the PET depolymerization catalyzed by Zn(Ac)2 under microwave irradiation were determined and studied via the method of GPC in 180℃,190℃ and 200℃ respectively.The tnorphologies of the undepolymerized PET observed by SEM was used for the comparation of using or no catalyst.The results shown that Zn(Ac)2 could accelerate the depolymerization rate significantly,and the catalytic effect in lower temperature was better than that in higher temperature.
