Bioconversion of ethylene glycol to glycolic acid for waste polyethylene terephthalate upcycling

Green Chemistry
Post-consumer PET is enzymatically depolymerized and upgraded via whole-cell biocatalysis to glycolic acid, enabling low-energy separation and high-value upcycling toward sustainable bio-based plastics.

In vivo and in vitro responses to poly(ethylene terephthalate-co-diethylene glycol terephthalate) and polyethylene oxide blends

Biomaterials, 1998
Although biocompatible polymeric compounds are generally nontoxic, nonimmunogenic, and chemically inert, implants made from these materials may trigger acute and chronic inflammatory responses. These inflammatory reactions may induce degeneration of implanted biopolymer.

Investigation of the state and distribution of water in poly(ethylene terephthalate)/polyethylene glycol copolymers with various molecular weight of polyethylene glycol

Polymer Engineering & Science, 2015
Poly(ethylene terephthalate)/polyethylene glycol (PETG) copolymers with molecular weight of PEG varied from 800 to 20,000 g/mol were synthesized by melt macromolecular interesterification method. The results of contact angle and water adsorption capacity reveal that the molecular weight of PEG has a positive effect on the hydrophilic behavior of PETG ...

Acidity and corrosivity of the volatile distillates in the synthesis of polyethylene terephthalate from dimethyl terephthalate and ethylene glycol

Fibre Chemistry, 1988
The acidity and aggressive properties of volatile distillates in the synthesis of polyethylene terephthalate from ethylene glycol and dimethyl terephthalate have been studied on industrial technological lines. It has been shown that the acidity of the distillates increases as the synthesis process approaches completion.

Polyphenylene Ether/Glycol Modified Polyethylene Terephthalate Blends and their Physical Characteristics

Journal of Macromolecular Science, Part B, 2011
Polyphenylene ether (PPE)/glycol modified polyethylene terephthalate (PETG) blends with various compositions were fabricated via a melt blending method using a laboratory-scale twin-screw extruder. The fracture surface morphology of the PPE/ PETG blends was examined by scanning electron microscopy (SEM) and, based on its data, it was observed that PPE ...

3D and 4D Printing of Polyethylene Terephthalate Glycol–Polypropylene Blends

Journal of Applied Polymer Science
ABSTRACTPolypropylene is one of the most widely used industrial thermoplastics, which, despite its high consumption in various industries, especially packaging, is not used much in the emerging field of 3D printing. In this article, for the first time, PETG is used in three weight percentages of 55%, 70%, and 85% to enhance polypropylene's printability,
