Synthesis of Radiation Curable Resin Derived from Poly (Ethylene Terephthalate) (PET) Wastes

Post-consumer beverage bottles were recycled by glycolysis in different molar ratios of PET/DEG, 1/1 and 1/2.15 at 200-205 °C in the presence of manganese acetate catalyst for 4 h to achieve an oligoester polyol. The hydroxyl values of obtained oligoesters were 130.8 and 159 mg KOH/g respectively. Modification of these oligoester polyols was carried out using acrylation reaction of hydroxyl functional groups by acrylic acid. This gave us acrylated oligoesters curable under UV irradiation.
