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 evolution of isoborylene, poly(acrylic acid) was produced. Trans-esterification reactions due to intermolecular interactions lead to evolution of H2O. Upon loses of CO2 and CO crosslinked units with higher thermal stabilities were generated. In case of P(MMA-co-IBA), intermolecular interactions between PIBA and PMMA chains were detected. Based on evolution of methanol, a trans-esterification reaction between the MMA and acrylic acid units generated by loss of isobornylene from PIBA chains was proposed.

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 ...
Pyrolysis of of poly(methy methacrylate) copolymers Ozlem-Gundogdu, Suriye; Gurel, Evren Aslan; Hacaloğlu, Jale (2015-05-01) In this work, thermal degradation of copolymers of poly(methy methacrylate) namely, poly(methyl methacrylate-co-n-butyl acrylate), P(MMA-co-nBu), poly(methyl methacrylate-co-n-benzyl methacrylate) P(MMA-co-BzMA, and poly(methyl methacrylate-co-isobornyl acrylate), P(MMA-co-IBA) were investigated via direct pyrolysis mass spectrometry. It was determined that whether an available gamma-H with respect to the carbonyl groups is present or not determines the thermal degradation mechanisms of polyacrylates and po...
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 ...
Pyrolysis mass spectrometry analysis of thiophene capped poly(methyl methacrylate) and poly(methylthienyl methacrylate) Hacaloğlu, Jale; Toppare, Levent Kamil (2003-06-01) The thermal degradations of thiophene-capped poly(methyl methacrylate) and poly(methylthienyl methacrylate) were studied via direct pyrolysis mass spectrometry. No significant effect of heating rate on the thermal degradation behaviors of the polymers under investigation have been observed in the heating range studied. It has been determined that thermal degradation of thiophene-capped poly(methyl methacrylate), (TPMMA) mainly yields monomer as in the case of pristine poly(methyl methacrylate). An analogous...
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...
