Optimization and characterization of glycolysis of waste polyethylene terephthalate (PET) with polyethylene glycol (PEG)

Chemical recycling of poly(ethylene)terephthalate(PET)has been the subject of increased interest as a valuable feedstock for different chemical processes.In this research, the glycolysis of PET will be studied using excess Polyethylene Glycol(PEG)as depolymerization agent assisted by magnesium aceta...
