rect pyrolysis mass spectrometric analysis of a styrene-butadiene-styrene block copolymer indicated that thermal decomposition of each block shows a resemblance to the related homopolymer, giving a possibility of differentiation of blocks. However, the random analog, the styrene butadiene rubber, degraded in a manner that is somewhat in between in nature of the thermal characteristics of both homopolymers. This technique shows promise to differentiate thermal behaviors of each sequence in block polymers if any exist. Indirect pyrolysis mass spectrometric analysis gave no clear evidence for differentiation of the nature and the composition of the copolymers.

Pyrolysis mass spectrometry analysis of BF4 - doped polythiophene
Gozet, Tuba; Hacaloğlu, Jale; Önal, Ahmet Muhtar (2004-06-01)
Pyrolysis of electrochemically prepared BF4- doped polythiophene (PTh) by direct insertion probe and Currie point pyrolysis gas chromatography mass spectrometry techniques indicated that thermal decomposition of PTh occurs in two steps. In accordance with literature results, the first step is assigned to the loss of the dopant, and the second step to the degradation of the polymer backbone producing segments of various conjugation lengths. At elevated temperatures, detection of products such as H2S and C2H2...
Pyrolysis mass spectrometry analysis of electrochemically grafted polyacrylonitrile with thiophene
Oguz, Gulcan; Hacaloğlu, Jale; Önal, Ahmet Muhtar (2005-10-01)
In this work, structural and thermal analyses of a polythiophene/polyacrylonitrile (PTh/PAN) sample, prepared by electrochemical polymerization of thiophene onto a poly(acrylonitrile) coated anode, have been performed by a direct insertion probe pyrolysis mass spectrometry technique. The evolution profiles of PTh based products from PTh/PAN showed nearly identical trends with those recorded during the pyrolysis of pure PTh. However, when PAN based products were considered, contrary to the trends observed fo...
Pyrolysis mass spectrometric analysis of copolymer of polyacrylonitrile and polythiophene
Oğuz, Gülcan; Hacaloğlu, Jale; Department of Polymer Science and Technology (2004)
In the first part of this work, the structural and thermal characteristics of polyacrylonitrile, polyacrylonitrile films treated under the electrolysis conditions in the absence of thiophene, polythiophene and the mechanical mixture and a conducting copolymer of polyacrylonitrile/polythiophene have been studied by pyrolysis mass spectrometry technique. The thermal degradation of polyacrylonitrile occurs in three steps; evolution of HCN, monomer, low molecular weight oligomers due to random chain cleavages a...
Pyrolysis of poly(phenylene vinylene)s with polycaprolactone side chains
Nur, Yusuf; Çolak, Demet; Cianga, Ioan; Yagci, Yusuf; Hacaloğlu, Jale (2008-05-01)
The thermal degradation characteristics of a new macromonomer poly(epsilon-caprolactone) with central 4,4'-dicarbaldehyde terphenyl moieties and poly(phenylene vinylene)s with well defined (E-caprolactone), (PPV/PCL) as lateral substituents were investigated via direct pyrolysis mass spectrometry. The unexpectedly high thermal stability of the macromonomer was attributed to intermolecular acetylation of benzaldehyde yielding a hemiacetal and causing a crosslinked structure during the pyrolysis. Increased th...
Thermal decomposition of polystyrene-b-poly(2-vinylpyridine) coordinated to co nanoparticles
Elmaci, Ayşegül; Hacaloğlu, Jale; Kayran, Ceyhan; Sakellariou, Georgios; Hadjichristidis, Nikos (2009-11-01)
Direct pyrolysis mass spectrometry analyses of polystyrene-block-poly(2-vinylpyridne), PS-b-P2VP, indicated that the thermal degradation of each component occurred independently through the decomposition pathways proposed for the corresponding homopolymers; depolymerization for PS and depolymerization and loss of protonated oligomers for P2VP by a more complex degradation mechanism. On the other hand, upon coordination to cobalt nanoparticles, thermal decomposition of the P2VP blocks was initiated by loss o...
