Polyethylene terephthalate (PET or PETE) is a general-purpose linear semicrystalline thermoplastic polymer. It belongs to the polyester family of polymers. These resins are known for their excellent combination of properties. These properties include mechanical, thermal, and chemical resistance as well as...
PET waste was depolymerised by alcoholysis with the help of 1-decanol. The obtained oligomeric plasticiser was characterised for its chemical structure using Fourier Transform Infrared Spectroscopy and Nuclear Magnetic Resonance. The prepared polymeric plasticiser was then used for the preparation of ...

Polyethylene terephthalate (PET) is high molecular weight polymer composed of ester bond-linked terephthalate (TPA) and ethylene glycol (EG)1. The durability and other favorable physical properties made PET one of the most extensively utilized plastic. However, the large amounts of PET that enters...
