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.

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

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(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 ...

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 ...

Enzymatic surface modification of poly(ethylene terephthalate)
Journal of Biotechnology, 2005This study unambiguously confirms hydrolysis using cutinase of the persistent synthetic polymer poly(ethylene terephthalate), the most important synthetic fiber in the textile industry by direct measurement and identification of the different hydrolysis products. In this aqueous heterogeneous system, dissolved cutinase from Fusarium solani pisi acts on

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.
