Poly(ethylene terephthalate)-PET and Poly(ethylene naphthalate)-PEN
, 2019 Since its discovery in 1930 by American chemist Wallace Hume Carothers and his coworkers, poly(ethylene terephthalate) (PET) attracted a great deal of attention by academic and industrial researchers. The new synthetic polymer, whose linear structure is built up by terephthalic acid and ethylene glycol units, was soon used for an extremely wide range ...

Microbial degradation and valorization of poly(ethylene terephthalate) (PET) monomers
World Journal of Microbiology and Biotechnology, 2022The polyethylene terephthalate (PET) is one of the major plastics with a huge annual production. Alongside with its mass production and wide applications, PET pollution is threatening and damaging the environment and human health. Although mechanical or chemical methods can deal with PET, the process suffers from high cost and the hydrolyzed monomers ...

Recycling of poly(ethylene terephthalate) (PET)
Makromolekulare Chemie. Macromolecular Symposia, 1992AbstractAfter a survey of the mostly utilized recycling methods for fibres and bottles, the possibilities of recovering films are discussed in more detail. This presentation describes primarily the melt‐recovery method, which is used by us and by other manufacturers.

Chemical recycling of poly(ethylene terephthalate) (pet) by hydrolysis and glycolysis
Environmental Science and Pollution Research, 2003In this paper we review an interesting method of PET recycling, i.e. chemical recycling; it is based on the concept of depolymerizing the condensation polymer through solvolytic chain cleavage into low molecular products which can be purified and reused as raw materials for the production of high-quality chemical products. In this work our attention is

Photo-Initiated Lamination of Polyethylene (PE) and Poly(ethylene terephthalate) (PET)
Journal of Adhesion Science and Technology, 2012Besides plasma-based processes, photo-initiated surface modifications have an interesting potential for adhesion promotion. This is of special interest with applications ranging from classical finishing to composites. Photo-chemical processes using continuous UV sources — monochromatic as well as broad band — are based on radical activation and ensuing

Crystallization of poly(ethylene terephthalate) (PET) from the oriented mesomorphic form
Journal of Applied Polymer Science, 1994AbstractYarns of different inherent viscosities, in the range 0.6–1.1 dL/g, spun in industrial plants, and drawn at room temperature to obtain mesomorphic samples, have been characterized. The evolution from the mesomorphic form toward the triclinic crystalline form has also been studied by combined differential scanning calorimetry (DSC), dynamic ...

Molar mass of poly (ethylene terephthalate) (PET) during ultimate uniaxial drawing
Polymer Engineering & Science, 2000AbstractThe changes of the average molar mass Mw, Mn, Mz, and molar mass distributions during multistep uniaxial drawing of poly(ethylene terephthalate) (PET) to achieve ultimate mechanical properties have been studied in detail by means of size exclusion chromatography (SEC) with triple detection: concentration, viscosimetry, and light scattering ...
