In this work, poly(methyl methacrylate), PMMA, composites involving various amounts of aromatic diboronic acid, BDBA, in the absence and presence of organically modified montmorillonite, Cloisite 30B, C30B, were prepared and characterized by X-ray diffraction, transmission electron microscopy, thermogravimetry, and direct pyrolysis mass spectrometry analyses. Morphologic analyses indicated homogenous dispersion of additives in PMMA matrix. Increase in thermal stability of PMMA was observed as the amount of BDBA incorporated into polymer matrix was increased. Strong evidences for interactions between the hydroxyl groups of diboronic acid and the ester groups of PMMA were detected. The increase in thermal stability was associated with these reactions producing also a cross-linked structure.

Poly(methyl methacrylate) organoclay composites; interactions of organic modifier with the polymer effecting thermal degradation behavior Ozdemir, Esra; Hacaloğlu, Jale (2017-10-01) In this work, poly(methyl methacrylate), PMMA, and its composites involving montmorillonites modified with different quaternary ammonium salts were prepared and characterized by X-ray Diffraction, XRD, Transmission Electron Microscopy, TEM, Thermogravimetry, TGA and direct pyrolysis mass spectrometry, DPMS. Increase in the interlayer spacing of the silicate layers compared to the corresponding organically modified clay was detected in X-ray diffractograms for all the PMMA composites in accordance with TEM r...
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...
Polylactide/organically modified montmorillonite composite fibers Ozdemir, Esra; Hacaloğlu, Jale (2017-03-01) Direct pyrolysis mass spectrometry technique was applied to investigate the characteristics of polylactide, (PLA) nanofibers containing organically modified montmorillonites, Cloisite 15A, (C15A) Cloisite 20A, (C20A) and Cloisite 30B, (GOB) prepared by electrospinning. As the amount of Cloisite present in the composites was increased, the fiber diameters became slightly narrower compared to neat PLA fiber due to the presence of quaternary ammonium salt as organic modifier increasing electrical conductivity....
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...
Preparation and thermal characterization of poly(2-vinylpyridine) copolymers coordinated to Cr nanoparticles Öztürk, Yurdagül; Kayran, Ceyhan; Hacaloğlu, Jale (2015-06-01) In this study, polystyrene-block-poly(2-vinylpyridine), PS-b-P2VP, polyisoprene-block-poly(2-vinylpyridne), PI-b-P2VP and poly(methyl metacrylate)-block-poly(2-vinylpyridine), PMMA-b-P2VP, coordinated to Cr metal were synthesized and characterized by Fourier transform infrared, transmission electron microscopy and direct pyrolysis mass spectrometry techniques. Both thermal degradation mechanism and thermal stability of P2VP blocks were affected by the coordination of Cr nanoparticles to nitrogen of pyridine...
