“…Further, these values are also better than those already reported for thermoplastic polyester elastomer (16.81 MPa). After blending with poly(butylene terepthalate) at 5:5, 7:3, 9:1, and 8:2, they showed tensile strengths of 23.38, 20.28, 18.25, and 18.72, respectively, which are found to be lower than that of our water‐dispersible polyester system. Further, WHBPs showed a yield point in the stress–strain profiles, but it is absent in WHBP0.…”

High‐performing water‐dispersible polyester synthesized under facile and ecofriendly reaction conditions has gained substantial interest because it has zero volatile organic compounds and is nontoxic. However, such polyester suffers from poor mechanical performance, so it is unsuitable for modern applications. In the present study, we focused on synthesis of a water‐dispersible polyester that contains aromatic and aliphatic moieties in the polymer backbone and can be readily synthesized from biobased and well‐defined reactants. We have synthesized water‐dispersible hyperbranched polyesters using three different weight percents of glycerol‐based hyperbranched polyol as a branch‐generating moiety containing both aromatic and aliphatic units along with citric acid, poly(ethylene glycol), and 2,2‐bis(hydroxymethyl) propionic acid through a solvent‐, catalyst‐, and neutralizing agent‐free facile route. The chemical structures of these polyesters were elucidated using various instrumental analyses. Hyperbranched epoxy and poly(amido amine) cured thermosets of these polyesters exhibited high tensile strength, toughness, impact resistance, scratch resistance, high gloss, biodegradability, and good chemical resistance without much effect on their elongation at break. Therefore, this high‐performing, sustainable, tough water‐dispersible thermosetting polyester has strong potential as an environmentally friendly polymeric material. © 2018 Wiley Periodicals, Inc. J.

“…Thermoplastic elastomer is a suitable blending material for PBT, as shown in several studies [8,[16][17][18][19]. Thermoplastic polyester elastomer (TPEE), a new member in the thermoplastic-elastomer (TPE) family, is suitable for blending with PBT [19]. Chemically, its hard segments are crystalline polyesters like those of PBT [20], making it compatible in blends [19].…”

Effects of Degraded Optical Fiber Sheaths on Thermal Aging Characteristics of Transformer Oil

et al. 2018

With the development of fiber optic sensing technology, optical fiber sensors have been widely used in online monitoring of power transformers. To investigate the influence of aging fiber sheaths on transformer oil, two kinds of special optical fibers with thermoplastic polyester elastomer (TPEE) and poly tetra fluoroethylene (PTFE) as sheaths underwent thermally accelerated aging in transformer oil at 130 °C. The volume resistivity, dielectric dissipation factor (DDF), and breakdown voltage of the oil were measured to indicate insulation strength. The water content and acid value of the oil were measured and fitted to predict the aging tends. The thermal aging characteristics of the oil were quantitatively compared and results showed two kinds of optical fibers could exacerbate all the physical and chemical parameters of oil, and the TPEE sheath had a more significant impact on the oil. The reasons contributing to such phenomenon were analyzed using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Both TPEE and PTFE were depolymerized in high-temperature transformer oils, producing water and small molecule hydrocarbon groups. The accumulation of small hydrocarbon groups promoted positive feedback of pyrolysis in the oil. The free hydrogen produced by oil pyrolysis increased the acidity of the oil, which in turn increased the solubility of the water produced by sheath depolymerization. The chain depolymerization of TPEE was more severe than that of PTFE, further exacerbating the deterioration of TPEE-containing oil.
