Polycondensation kinetics of poly(ethylene terephthalate) and poly(butylene terephthalate)
Polymer, 1986Abstract The polycondensation kinetics of poly(ethylene terephthalate) (PET) and poly(butylene terephthalate) (PBT) in the absence of catalyst are found to be of different nature. By means of a set of multiparameter kinetic equations, the kinetic behaviour of PET polycondensation can be simulated numerically; the cause of the disparity is found to be

Enzymes for the Biofunctionalization of Poly(Ethylene Terephthalate)
2010The functionalization of synthetic polymers such as poly(ethylene terephthalate) to improve their hydrophilicity can be achieved biocatalytically using hydrolytic enzymes. A number of cutinases, lipases, and esterases active on polyethylene terephthalate have been identified and characterized.

Degradation of poly(ethylene terephthalate) catalyzed by metal-free choline-based ionic liquids
Green Chemistry, 2020Glycolysis of PET is a prospective way for degradation of PET to its monomer bis(hydroxyethyl)terephthalate (BHET) which can be polymerized again to form new qualified PET materials, and hence provides possibilities for a permanent loop recycling.

Polymer, 2005
Abstract Uniaxial and plane strain compression experiments are conducted on amorphous poly(ethylene terephthalate) (PET) and poly(ethylene terephthalate)-glycol (PETG) over a wide range of temperatures (25–110 °C) and strain rates (.005–1.0 s −1 ).

Powdered poly(ethylene terephthalate)
Die Angewandte Makromolekulare Chemie, 1980AbstractThe influence of the conditions of preparation on the properties of powdered poly(ethylene terephthalate) was followed from the point of view of its specific surface. The powdered poly(ethylene terephthalate) prepared by reprecipitation from the melt of 6‐caprolactam has a porous and structured surface, and consequently, also a large specific ...
