Glycolytic recycle of poly(ethylene terephthalate) (PET)
Makromolekulare Chemie. Macromolecular Symposia, 1992AbstractIn a comparison of PET waste recovery methods, glycolysis to monomer (DHET + low MW oligomers) represents a compromise between regeneration of starting ingredients by methanolysis or hydrolysis and direct remelt extrusion. It is less costly than the former and more versatile than the latter.

Impact Response of Waste Poly Ethylene Terephthalate (PET) Composite Plate
2016Poly ethylene terephthalate (PET) is considered one of the most important engineering polymers for the last two decades due to its rapid growth of usage, aesthetic appearance, good light transmittance, and smooth surface. It is highly preferable for the food and soft drink bottle packaging industry because of its low gas permeability and recycling ...

Characterization of virgin and recycled poly(ethylene terephthalate) (PET) fibers
The Journal of The Textile Institute, 2014In this study, we compared the properties of recycled poly(ethylene terephthalate) (PET) fibers and virgin PET fibers. All these experiments present the differences or similarities between them on surface morphology, mechanical properties, and internal fiber structure.

Kinetic model for the pyrolysis and combustion of poly-(ethylene terephthalate) (PET)
Journal of Analytical and Applied Pyrolysis, 2001Abstract The kinetics of the global primary thermal decomposition of poly-(ethylene terephthalate) (PET) waste was studied in strict pyrolysis conditions and with different proportions of oxygen by TGA, between temperatures of 25 and 800°C. Prior to the decomposition, the polymer first melts at around 250°C.

How to Make Colorless Poly(ethylene terephthalate)(PET)
International Journal of Polymeric Materials, 2001Abstract The methods and flow charts used for the industrial preparation of PET are shown and briefly discussed. Then, the three classes of contaminants usually appearing in PET are described and their causes elucidated. The organic contaminants impart to the produced PET an undesired yellow-amber tinge while those containing metal ions or elemental ...

Polymer Bulletin, 2018
The esterification step during poly(ethylene terephthalate) (PET) polymerization was studied using ethylene glycol (EG) and terephthalic acid (TPA), together with microwave radiation in a closed system. First, the effects of temperature and molar ratio EG/TPA on the number-average molecular weight (

Environmental Science and Pollution Research, 2018
In the present study, the recycled post-consumption polyethylene terephthalate (PET) flakes were investigated as possible raw materials for the production of food packaging. After heating at 220 °C for 1 h, a steaming stage was conducted as a control test to assess the quality of the product.

Polymer Degradation and Stability, 2015
The alkali resistance of poly(ethylene terephthalate) (PET) and a series of poly(ethylene glycol-co-1,4-cyclohexanedimethanol terephthalate) (PETG) copolyesters with different molar ratios of ethylene glycol (EG) to 1,4-cyclohexanedimethanol (CHDM) was systematically investigated. Differential scanning calorimetry (DSC) and wide-angle X-ray diffraction

Physical aging studies in amorphous poly(ethylene terephthalate) (PET) blends
Thermochimica Acta, 1990Abstract Physical aging phenomena of amorphous poly(ethylene terephthalate) (PET) blends have been investigated. Blends modified with dioctylphthalate (DOP), a miscible plasticizer, have shown a significant reduction in the glass transition temperature, while rubber modified blends exhibit no change in Tg.
