“…This corresponds to the influence on the order of the degradation reaction. It is clear that the selection of blending technique is more critical in the case of compatibilized blends which can cause a big impact on thermal stability via activation energy and order of the degradation reaction …”

The present work describes the influence of processing route on thermomechanical properties of thermoplastic polyurethane (TPU) and polydimethylsiloxane (PDMS) compatibilized blends. In this study, compatibilized blends of TPU and PDMS prepared by melt mixing and solution mixing techniques were compared. Ethylene methyl acrylate at different doses of 1, 2, 3, and 4 phr was used as the compatibilizer in 90:10, 80:20, and 70:30 blend ratios of TPU and PDMS. Optimum percentage of compatibilizer was same in both the methods and which was increased with the percentage of PDMS. As compared to melt mixed blends, solution mixed blends showed improved mechanical properties. From the dynamical mechanical analysis it was observed that the glass transition temperature (Tg) obtained was higher for the solution mixed blends due to the stiffer chains. The enhanced physicomechanical properties of the solution mixed blends were attributed to the improved thermal stability of the blends. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…54 In TPU-PSS/DVB membranes, initial weight loss up to 160 C can be attributed to residual moisture and solvent (MEK) loss in the membranes. The onset of TPU degradation is evident at around 370 C involving degradation of hard segment in the form of disassociation of urethane into polyol and isocyanate that continues up to 450 C. 55 The third degradation step starting around 460 C can be related to the degradation of so segment involving breakage of bonds formed through polycondensation and polyol degradation that continues up to 600 C. 16…”

“…When the decomposition temperature traversed, the sample will become heat-sensitivity and experience structural deformation, forming oxides; this will bring about the mass decrement and, in turn, will betoken the sample's thermal stability. From the TG curves, the thermal degradation components such as incipience degradation, the temperature at which the highest rate of degradation, temperatures at distinctive mass losses, and also [40,41].…”

The medleys of the plastic-derived polypeptide with commercially available polymers believably the suitable candidate for pharmaceutical and biomedical importance. The current research is focussed on the synthesis of a novel plastic-mimetic polypeptide (PLP), poly(IPAVG) by the solution phase method (where I, P, A, V, and G represent Isoleucine, Proline, Alanine, Valine, and Glycine, respectively). The miscibility attributes of PLP/polyvinyl alcohol (PVA) and PLP/ hydroxypropylmethylcellulose (HPMC) blends were examined by viscometry and by other advanced analytical tools for different weight proportions. It is shown by the viscometry that the PLP/HPMC and PLP/PVA form an immiscible blend system at 10 ο C and further, the FTIR spectra of poly (IPAVG) /HPMC and poly (IPAVG) /PVA blend membranes manifest the lack of intermolecular interactions. DSC results proved the dual Tg for one blend proportion and lower Tg values for all other blend systems. The thermal property of the blends with different compositions was evaluated by thermogravimetric analysis (TGA). The TGA results showed that the blends possess inferior thermal stability to the native ones. The surface morphology was analyzed by SEM indicated the heterogeneity and X-ray diffraction (XRD) revealed the absence of any change in crystallinity advocated the immiscibility of the blends. Further, we ventured to prepare the non-woven fabrics from the solutions of 1-10 wt% concentrations at the voltages within 20-30 kV by electrospinning. The droplet formed at the spinneret failed to reach the collector plate, and consequently, no films developed for the collector device.
