Synthesis of Biodegradable Low-Molecular-Weight PBAT from RecycledPET

Environmental pollution significantly impacts daily life, with plastic waste contributing toenvironmental degradation. Recycling polymers, particularly those that are not easily recyclable, isessential for mitigating this issue. This research focuses on recycling PET, a widely used polymer,through glycolysis to produce BHET as the monomer for the synthesis of biodegradable PBATpolymer with low molecular weight, a promising candidate to be used in food packaging andagricultural films. The FTIR results confirm the formation of BHET and PBAT. Also, the molecularweight of the synthesized polymer is determined to be ۴۴۳۵۵.۸۵ g/mol. This study highlights thepotential of recycling PET into biodegradable polymers, contributing to environmental sustainability.
