Molecular Weight and its Distribution of PET Depolymerization Residue under Microwave Irradiation

Abstract:

The molecular chain of PET would be broken in the process of depolymerization reactions under microwave irradiation, which would lead to changes in molecular weight. In this paper, the molecular weight of PET residue measured by gel permeation chromatography (GPC) was used to track the progress of PET depolymerization. The results showed that the molecular weight of the residue after depolymerization under 180°Cdecreases as reaction time increases, however when the temperature of depolymerization was 190°Cor 200°C, with the reaction time increases, the molecular weight of residue decreased first and then increased slightly.
