Thermal degradation of polystyrene (PS) involving brominated polyepoxy (BA) and antimony oxide (PS/BE/Sb2O3) was studied systematically via direct pyrolysis mass spectrometry. Thermal decomposition of brominated polyepoxy was started by loss of end groups. The relative yields of high mass thermal degradation products of PS and the product distribution of brominated polyepoxy and antimony oxide were changed noticeably during the pyrolysis of PS/BE/Sb2O3 composite. Its thermal decomposition was initiated by the interactions of Sb2O3 with BE, and shifted to lower temperatures. Interactions of flame retardants with PS caused degradation of PS at lower temperatures to a certain extent. Loss of HBr and H2O, in the temperature region where main PS decomposition took place, confirmed chemical interactions between the flame retardants and PS.

Thermal degradation of polystyrene composites. Part II. The effect of nanoclay KAYA, Hatice; Kaynak, Cevdet; Hacaloğlu, Jale (2016-07-01) In this work, thermal degradation behavior polystyrene/organoclay nanocomposites containing tribromophenol end-capped brominated epoxy oligomer, (BE) with or without Sb2O3 were investigated systematically via direct pyrolysis mass spectrometry. Incorporation of organically modified montmorillonite into polystyrene, (PS) matrix not only increased thermal stability but also the probability of radical recombination, disproportionation and carbonization reactions causing increase in the char yield. Exfoliation ...
Thermal degradation of poly(propylene oxide) and polyepichlorohydrin by direct pyrolysis mass spectrometry Uyar, T; Hacaloğlu, Jale (2002-09-01) The thermal degradation of poly(propylene oxide), (PPO) and polyepichlorohydrin, (PECH) were studied with the use of direct pyrolysis mass spectrometry. The effects of heating rate and dissociative ionization on fragmentation pattern have also been investigated. It has been determined that PPO degrades via a random cleavage mechanism, the labile C-O bond scissions being preferred, An analogous degradation mechanism can be proposed for PECH. Yet, the elimination of side chains, evolution of HCl and the loss ...
Thermal degradation of Polylactide/Poly(ethylene glycol) fibers and composite fibers involving organoclay Ozdemir, Esra; Hacaloğlu, Jale (2018-01-01) In this study, electrospun fibers of melt blended poly(lactic acid) and poly(ethylene glycol), (PLA)-PEG blends involving 10, 15 and 20 wt% PEG and their corresponding composites with organically modified montmorillonite, Cloisite 30B were prepared and characterized by x-ray diffraction, differential scanning calorimetry, thermogravimetry and direct pyrolysis mass spectrometry techniques. The narrower fiber diameters observed for the PLA-PEG fibers involving organoclay compared to the corresponding neat fib...
Thermal degradation of poly(isobornyl acrylate) and its copolymer with poly(methyl methacrylate) via pyrolysis mass spectrometry Ozlem, Suriye; Aslan-Guerel, Evren; Rossi, Rene M.; Hacaloğlu, Jale (2013-03-01) In this work, the thermal degradation characteristics of poly(isobornyl acrylate) (PIBA), and its copolymer with PMMA, P(MMA-co-IBA) were investigated via direct pyrolysis mass spectrometry. Thermal degradation behavior of poly(isobornyl methacrylate) (PIBMA) was also studied for a better understanding of thermal degradation mechanism of PIBA. For both PIBA and PIBMA, gamma-H transfer from the isobornyl ring to the carbonyl group was predominantly effective in thermal degradation. As a consequence of evolut...
Polylactide/organically modified montmorillonite composites; effects of organic modifier on thermal characteristics Ozdemir, Esra; Öztürk, Yurdagül; Hacaloğlu, Jale (2016-12-01) The effects of interspace distance and the possible chemical interactions between PLA and the organic modifier of montmorillonites, Cloisite 15A, 20A and 30B on thermal degradation of PLA in the absence and presence of water vapor were investigated by direct pyrolysis mass spectrometry, (DP-MS) in addition to XRD, TEM, DSC, TGA analyses. The DP-MS results clearly showed that the way in which the polymer was incorporated into the nanocomposite strongly depends on the mixing technique, the interspacing betwee...
