Thermal degradation behaviors of phenol and benzoxazine end-capped polysulfone macromonomers (PSU-OH and PSU-P-a) and pre-cured PSU-P-a in the absence and presence of aniline and phenol based benzoxazine monomer (P-a) were investigated via pyrolysis mass spectrometry. A significant increase in thermal stability of both polysulfone and polybenzoxazine chains upon polymerization of benzoxazine end groups was determined compared to phenol-ended polysulfones and aniline based monofunctional polybenzoxazine. Thermal stability of both chain segments depends on concentration of benzoxazine monomer and the chain length of the polysulfone chain

Thermal degradation of polysiloxane and polyetherester containing benzoxazine moieties in the main chain Bagherifam, Shahla; Kışkan, Barış; Aydogan, Binnur; Yagci, Yusuf; Hacaloğlu, Jale (2011-01-01) In this study investigation of thermal characteristics of polysiloxane and polyetherester containing benzoxazine moieties in the main chain was performed via pyrolysis mass spectrometry. Pyrolysis mass spectrometry analyses revealed that the thermal stability and the extent of cross-linking enhanced when the benzoxazine moieties were separated by thermally more stable units such as siloxanes. However, when the siloxane chain units were long, possibility of polybenzoxazine growth decreased significantly and ...
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 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 degradation of polystyrene composites. Part I. The effect of brominated polyepoxy and antimony oxide Kaya, Hatice; Hacaloğlu, Jale (2014-01-01) 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 t...
Thermal decomposition of glycidyl azide polymer by direct insertion probe mass spectrometry Fazlioǧlu, Hatice; Hacaloğlu, Jale (2002-01-01) Thermal decomposition reactions and products of glycidyl azide polymer (GAP), have been investigated by direct insertion mass spectrometry and evolved gas analyses by FTIR spectroscopy techniques. It has been observed that thermal degradation of GAP begins with cleavage of the side groups. Although the main decomposition started with the elimination of molecular nitrogen from the azide functional group, degradation initiated by loss of N-3 and CH2N3, depolymerization type reactions were also identified. Rea...
