Current Knowledge on Polyethylene Terephthalate ...

 · The global production of polyethylene terephthalate (PET) is estimated to reach 87.16 million metric tons by 2022. After a single use, a remarkable part of PET is accumulated in the natural environment as plastic waste. Due to high hydrophobicity and high molecular weight, PET is hardly biodegraded by wild-type microorganisms.

Polyethylene Terephthalate - GeeksforGeeks

 · Polyethylene Terephthalate (PET) A polyethylene terephthalate is a terephthalic acid and ethylene glycol condensation polymer. Water is a by-product of the reaction that produces this molecule, hence it is an example of step-growth polymerization or condensation. There are two types of polymerization based on this mechanism.

The Crystal Structure of Polyethylene Terephthalate
