Annealing of poly (ethylene terephthalate)

European Polymer Journal, 2014
Abstract Poly (ethylene terephthalate), PET, crystallized isothermally at 234 °C has been annealed above the crystallization temperature in regimes II, below the onset of melting, and in regime III, in the range of observable melting [1] , [2] . The mechanism has been analyzed by differential scanning calorimetry and FTIR spectroscopy and shown to ...

Poly(Ethylene Terephthalate) Microplastics

2021
The high PET production volume and the waste mismanagement of PET litter make it one of the most polluting plastic material. Its diffusion in marine litter is widely assessed according to public opinion and documented in the literature. The major sources of PET microplastics in the marine environment are bottles and fibers.

Structure of poly(ethylene terephthalate)

Journal of Macromolecular Science, Part B, 1967
Abstract This article summarizes electron microscopy, X-ray diffraction, and infrared spectroscopy examinations of poly(ethylene terephthalate) which have been published in recent issues of the Journal of Macromolecular Science—Physics [1-3]. The structure of glassy poly(ethylene terephthalate) and the effect of crystallization from the glass by ...

Flame‐retardant poly(ethylene terephthalate)

Journal of Applied Polymer Science, 1975
AbstractPoly(ethylene terephthalate) containing hexabromobenzene, tricresyl phosphate, or a combination of triphenyl phosphate and hexabromobenzene, pentabromotoluene, or octabromobiphenyl was extruded or spun at 280°C into monofilaments or low‐denier yarn, respectively.

Poly(ethylene terephthalate)/cellulose blends

Journal of Applied Polymer Science, 1985
Amorphous poly(ethylene terephthalate) (PET) and cellulose blends in film form were obtained by room temperature hydrolysis of PET/cellulose trifluoroacetate solution cast films. Evidence is presented indicating that the cellulose, or the water associated with it, nucleates the crystallization of the PET during differential scanning calorimetry (DSC ...

Properties of poly(ethylene terephthalate)/poly(ethylene naphthalate) blends

Polymer Engineering & Science, 1999
AbstractBlends composed of poly(ethylene terephthalate) (PET) as the majority component and poly(ethylene naphthalate)(PEN) as the minority component were melt‐mixed in a single screw extruder at various PET/PEN compound ratios. Tensile and flexural test results reveal a good PET/PEN composition dependence, indicating that the compatibility of the ...

Mechanically Linked Poly(ethylene terephthalate)

Macromolecules, 2004
The synthesis, by solid-state copolymerization, and properties of poly(ethylene terephthalate) (PET) copolymers containing various amounts of [2] catenane mechanical linkages are described. Polymers end-capped by the corresponding noninterlocked macrocycle as well as a copolymer with a rigid fluorene monomer unit were also prepared as reference systems.

Poly(ethylene terephthalate)

2009
Abstract Major Applications Fibers, films, barrier film, soft drink bottle (amorphous PET), film for compression molding PE, PP, and for replacement of commodity metals such as steel and aluminum (1–3). Copolymers of PET are proposed for use as fire retardants (4) and biodegradable films (5, 6).

Nucleation in poly(ethylene terephthalate)

Acta Polymerica, 1982
AbstractMeasurements of isothermal crystallization kinetics of poly(ethylene terephthalate) including defined solid nucleating agents have been performed by DSC method in broad temperature range. Based on the results and knowledge of growth rate of spherulities in PETP the nucleation rates were calculated.
