Solubility of Polyethylene Terephthalate

Nature, 1965
IT is generally considered that polyethylene terephthalate is soluble only in a restricted range of rather specialized organic liquids, such as o-chlorophenol, tetrachlorethane/phenol, etc. It is the purpose of this report to describe conditions under which this range may be extended.

Easily recoverable and reusable p-toluenesulfonic acid for faster hydrolysis of waste polyethylene terephthalate

Green Chemistry, 2022
Common technologies for waste polyethylene terephthalate (PET) hydrolysis generally use strong acids or alkalis as catalysts; however, these processes are costly and generate a large amount of acid, alkali, and...

Polyethylene terephthalate (PET) in the packaging industry

, 2020
Polyethylene terephthalate (PET) is the third most widely diffused polymer exploited in the packaging industry, monopolizing the bottles market for beverages, and covering almost the 16% of the European plastic consumption in the packaging industry. Even

Dihydroxy Polyethylene Additives for Compatibilization and Mechanical Recycling of Polyethylene Terephthalate/Polyethylene Mixed Plastic Waste.

ACS Macro Letters, 2022
Polymer blend compatibilization is an attractive solution for mechanical recycling of mixed plastic waste because it can result in tough blends. In this work, hydroxy-telechelic polyethylene (HOPEOH) reactive additives were used to compatibilize blends ...

Aminolysis of polyethylene terephthalate

Polymer, 1963
Abstract By treating polyethylene terephthalate fibres with solutions of hydrazine, benzylamine, ethylenediamine, hexamethylenediamine, piperidine and aniline the following amides of terephthalic acid and oligomeric diacids have been obtained: terephthalic dihydrazide, terephthalic bis-benzylamide, bis-benzylamides of oligomers, probably dimer and ...

Hydrolysis of waste polyethylene terephthalate catalyzed by easily recyclable terephthalic acid.

Waste Management, 2021
Hydrolysis of polyethylene terephthalate (PET) is an efficient strategy for the depolymerization of waste PET to terephthalic acid (TPA), which can be used as a fundamental building block for the repolymerization of PET or for the synthesis of ...

Polyethylene Terephthalate Blends

International Polymer Processing, 1988
Abstract Polymer-Polymer blends containing ethylene-methacrylic copolymers (EMAA) and polyethylene terephthalate (PET) (where PET is the minor component) have been investigated. The permeability properties and the morphology of these blends, when the polyolefin phase is mildly crosslinked with small amounts of an agent that ...
