Poly(ethylene terephthalate) fibres
1997Poly(ethylene terephthalate), or PET, is the most outstanding member of the family of polyester fibres. Polyester is defined by the International Standards Organisation (ISO) as ‘a polymer comprising synthetic linear macromolecules having in the chain at least 85% (by mass) of an ester of a diol and terephthalic acid’ [1]. A comprehensive compendium on

Photolysis of poly(ethylene terephthalate)
Journal of Polymer Science Part A-1: Polymer Chemistry, 1967AbstractThe photolysis of poly(ethylene terephthalate) films was studied in vacuo with light of wavelengths 2537 and 3130 A. A very stable filter system which cuts out the 3025 A. line was developed to isolate 3130 A. from a mercury spectrum. Despite the fact that the penetration of 2537 A. light was limited to a depth of a ca. 103 A.

Pressure effect on the melting behavior of poly(butylene terephthalate) (PBT) and poly(hexamethylene terephthalate) (PHT) was studied by high-pressure DTA (HP-DTA) up to 320 and 530 MPa, respectively. Cooling rate dependence on the DSC melting curves of the samples cooled from the melt was shown at atmospheric pressure.

Poly(ethylene terephthalate) yarn with antibacterial properties
Journal of Biomaterials Science, Polymer Edition, 2001Poly(ethylene terephthalate) (PET) yarn with grafted poly(acrylic acid) (poly(AA)) was loaded with [6R-[6alpha,7beta(Z)]]-7-[[2-amino-4-thiazolyl)(methoxy-imino)acetyl]aminol-8-oxo-3-[[(1,2,5,6-tetrahydro-2-methyl-5,6-dioxo-1,2,4-triazin-3-yl)thio]-methyl]-5-thia-1-azabicyclo[4.2.0] oct-2-ene-2-carboxylic acid (Lendacin), a cephalosporin-type ...

The Degradation of Poly(ethylene terephthalate)
Angewandte Chemie International Edition in English, 1968AbstractThe penetration of new markets by polyester fibers has emphasized the need for increased stability of the polyester toward a variety of degradative reactions. Extensive studies of the nature of the thermal, hydrolytic, oxidative, and radiation‐induced degradation reactions have been reported. The interpretation of kinetic investigations and the

A bacterium that degrades and assimilates poly(ethylene terephthalate)
Science, 2016Some bacteria think plastic is fantastic Bacteria isolated from outside a bottle-recycling facility can break down and metabolize plastic. The proliferation of plastics in consumer products, from bottles to clothing, has resulted in the release of countless tons of plastics into the environment. Yoshida

Poly(Ethylene Terephthalate) Microplastics
2021The 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.

Antioxidants for poly(ethylene terephthalate)
1998Polymers undergo oxidation reactions when heated in air. Heating of the polymer takes place at any stage of the life of the polymer, e.g. during polymerization, processing or end use of the ready product. Oxidation results in chain scission, branching, crosslinking or formation of oxygen-containing functional groups and leads to deterioration of ...

Polymer, 1998
The miscibility behaviour of melt-mixed poly(ethylene terephthalate-co-diethylene glycol terephthalate) [PET-co-DEGT] with poly(ethylene oxide) was investigated in all composition ranges. The crystallization of the semicrystalline blend component at different compositions was evaluated by optical microscopy with crossed polarizers.
