Enzyme and Microbial Technology, 2021
Poly(ethylene terephthalate) (PET) is a class of polyester plastic composed of terephthalic acid (TPA) and ethylene glycol (EG). The accumulation of large amount of PET waste has resulted in severe environmental and health problems. Microbial polyester hydrolases with the ability to degrade PET provide an economy- and environment-friendly approach for ...

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 ...

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

Comparative techniques for molecular weight evaluation of poly (ethylene terephthalate) (PET)
Polymer Testing, 2005 Abstract The molecular weight evaluation of poly(ethylene terephthalate) (PET) from different sources was accomplished by using three different techniques: solution intrinsic viscosity, intrinsic viscosity from melt flow index (MFI) and size exclusion chromatography (SEC).

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

Polymer, 2003
The multiple melting behavior of poly(ethylene terephthalate) (PET) homopolymers of different molecular weights and its cyclohexylene dimethylene (PET/CT) copolymers was studied by time-resolved simultaneous small-angle X-ray scattering/wide-angle X-ray scattering diffraction and differential scanning calorimetry techniques using a heating rate of 2 °C/
