“…The nickel and copper transition metal complexes of this polymer exhibited the properties of soft ferromagnetic materials. In another study, He et al [8] reported a novel Schiff base type polyester containing 2,2'-diamino-4,4'-bithiazole prepared by low-temperature interface polycondensation of 1,4-benzenedicarbonyl dichloride with a diphenol compound derived from a 2,2'-diamino-4,4'-bithiazole Schiff base reacted with a 4-hydroxybenzaldehyde monomer. They characterized the synthesized polymer using FTIR spectroscopy, elemental analysis and X-ray diffrac-tion.…”

A new conjugated polymer containing a bithiazole group is prepared by the polycondensation of 2,2'-diamino-4,4'-bithiazole and terephthaldialdehyde in the presence of glacial acetic acid. The kinetics of thermal degradation of the new polymer are investigated by thermogravimetric analysis at different heating rates. The temperature corresponding to the maximum rate loss shifts to higher temperatures with increasing heating rate. The thermal decomposition activation energies of the conjugated polymer in a conversion range of 3–15 % are 288.4 and 281.1 kJ/mol by the Flynn–Wall–Ozawa and Kissinger methods, respectively. The Horowitz–Metzger method shows that the thermodegradation mechanism of the conjugated polymer proceeds over a three-dimensional diffusion type deceleration D3 mechanism. The optimum heating rate is 20 ºC/min.

Kinetic of thermal degradation and thermal stability of natural rubber filled with titanium dioxide nanoparticles

et al. 2018

This article deals with the kinetic of thermal degradation and thermal stability of natural rubber (NR) filled with titanium dioxide (TiO2) nanoparticles. Incorporation of TiO2 nanoparticles was done through a latex mixing method. This is to ensure the homogeneity of TiO2 nanoparticles throughout the NR matrix. Adding TiO2 nanoparticles results in shifting the decomposition temperature and char residue irrespective of the loadings of TiO2 nanoparticles. This is confirmed by the calculated kinetic parameters of the composites, indicating that higher energy is required to decompose the NR chains. Based on this analysis, a schematic model for thermal stability of TiO2 nanoparticles filled NR composites is proposed. POLYM. COMPOS., 40:3149–3155, 2019. © 2018 Society of Plastics Engineers

Recycling of rubber waste and searching for alternative routes to prolong the service life of rubber products are of significant concern. One of the ideas to reduce the rubber waste is to blend it with the virgin rubber to gain synergistic properties from its own advantages. In this study, natural rubber (NR) and recycled ethylene propylene diene rubber (R-EPDM) were blended as a way to combine the mechanical properties and oxidative resistance given by NR and R-EPDM, respectively. New approaches in enhancing the thermal stability were observed through the use of bio-compatibilizers that is, alkanolamide (AKA)-based refined, bleached, and deodorized palm stearin (RBDPS) and NR latex (NRL). The thermal stability of the blends was monitored through two techniques: thermo-oxidative aging and thermogravimetric Analysis. Results indicated that the aging resistance of the blends was improved by addition of AKA and NRL as bio-compatibilizers. This is confirmed by the enhancement of thermal decomposition temperature and the activation energies of the blends. The obtained TG profiles and the calculated kinetic parameters indicated that introducing AKA and NRL enhanced their thermal stability, especially at higher contents of AKA and NRL. J. VINYL ADDIT.
