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 ...

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 ...

Poly(butylene terephthalate) poly(ethylene terephthalate) mixtures formed by ball milling
Materials Research Bulletin, 1999Mixtures of poly(butylene terephthalate) (PBT) and poly(ethylene terephthalate) (PET) polymers were formed using ball milling technique and characterized by means of differential scanning calorimetry (DSC) and X-ray diffraction (XRD). PET with different degrees of crystallinity was used in the solid-state mechanical milling process.

Crystallization of Poly(ethylene terephthalate)
1968It has been reported that several endothermic melting transitions exist in differential thermal analysis thermograms of polyethylene.1 Similar transitions are reported in differential scanning calorimetric thermograms of poly (ethylene terephthalate)2 and bisphenol-A polycarbonate.3 The appearance of separate melting endotherms in these polymers is ...

Ultrasound-enhanced enzymatic hydrolysis of poly(ethylene terephthalate)
Bioresource Technology, 2016The application of ultrasound was found to enhance enzymatic hydrolysis of poly(ethylene terephthalate) (PET). After a short activation phase up to 6.6times increase in the amount of released products was found. PET powder with lower crystallinity of 8% was hydrolyzed faster when compared to PET with 28% crystallinity.

Wide-Angle X-ray Diffraction (WAXD) and Small-Angle X-ray Scattering analyses were carried out to evaluate the evolution of the crystalline and supermolecular structure of poly(ethylene terephthalate) (PET) blended with poly(trimethylene terephthalate) (PTT). The conditions adopted in preparing the PET/PTT 50/50 blend induce transesterification between

Poly(ethylene terephthalate)-PET and Poly(ethylene naphthalate)-PEN
2019Since its discovery in 1930 by American chemist Wallace Hume Carothers and his coworkers, poly(ethylene terephthalate) (PET) attracted a great deal of attention by academic and industrial researchers. The new synthetic polymer, whose linear structure is built up by terephthalic acid and ethylene glycol units, was soon used for an extremely wide range ...

Journal of Polymer Science Part A: Polymer Chemistry, 1996
The effects of transesterification on the miscibility of poly(ethylene terephthalate)/poly(ethylene 2,6-naphthalate) were studied. Blends were obtained by solution precipitation at room temperature to avoid transesterification during blend preparation.

Thermal properties of Poly(trimethylene terephthalate)/Poly(ethylene terephthalate) melt blends
Fibers and Polymers, 2003The thermal behavior, morphology, ester-interchange reaction of Poly(trimethylene terephthalate) (PTT)/Poly(ethylene terephthalate) (PET) melt blends were investigated over the whole composition range(xPTT/(1-x)PET) using a twinscrew Brabender. The melt blends were analyzed by differential scanning calorimetry (DSC), nuclear magnetic resonance ...
