PURIFICATION OF RECYCLED TEREPHTHALIC ACID AND SYNTHESIS OF POLYETHYLENE TEREPHTHALATE

, 2019
Plastic waste pollution presents one of the major environmental challenges in the 21. Century. Post-consumer textile waste is especially problematic since it is very hard to recycle mechanically due to the high content of various impurities. Therefore routes for chemical recycling needs to be developed.

Nanoplastics in Depolymerization Products from Hydrolysis of Poly(Ethylene Terephthalate) in the Solid State

Macromolecular Rapid Communications, EarlyView.
Hydrolysis of PET in the solid generates nanoparticles, but thermal signatures of PET were only observed for hydrolysis at 150°C, while oligomers appeared to dominate the non‐monomeric products from hydrolysis at higher temperatures. ABSTRACT Circularity in plastic waste management through depolymerization to monomer is a promising route to address ...

Highly Degradable Polyester With Chemical and Thermal Stability Utilizing Oxidative Degradation of 2‐Thioethyl Ester

Journal of Polymer Science, EarlyView.
Polyester with the structure of 2‐thioethyl ester reveals oxidative degradability via the oxidation to sulfone followed by base‐promoted β‐elimination. Since the degradation occurs by the nonnatural stimuli, these polymers are stable during use but can be degraded at the desired instant after use.
