This study investigates treating polyethylene terephthalate (PET) waste water bottles with different mass of ethylene glycol (EG)\nusing reactive extrusion technique at a temperature of 260âË?Ë?C. The study puts emphases on evaluating the thermal, mechanical, and\nchemical characteristics of the treated polyethylene terephthalate.Theproperties of the treatedPET fromthe extruderwere analyzed\nusing FT-IR, TGA, DSC, and nanoindentation.The melt flow indexes (MFI) of both treated and untreated PET were alsomeasured\nand compared. Thermal properties such as melting temperature (
