Direct pyrolysis mass spectrometry is applied to investigate the thermal behavior of poly(2-isopropyl-2-oxazoline) (PIPOX, a thermoresponsive polymer) and poly[2-(3-butenyl)-2-oxazoline] (PBOX, a clickable polymer). It is found that the thermal degradation of PIPOX is started by a loss of side chains. At slightly higher temperatures the degradation of the polymer backbone occurs by random chain scission processes. In the case of PBOX, vinyl polymerization of the side chains produces chains with variable thermal stabilities. The number of repeating units of the polymer has almost no effect on the thermal behavior of PIPOX, but significantly affects both thermal stability and degradation product distribution of PBOX.

Direct pyrolysis mass spectrometry studies on thermal degradation characteristics of poly(phenylene vinylene) with well-defined PSt side chains Nur, Y.; Çolak, Demet; Cianga, I.; Yagci, Y.; Hacaloğlu, Jale (2008-10-01) Thermal degradation characteristics of a new macromonomer polystyrene with central 4,4'-dicarbaldehyde terphenyl moieties and poly(phenylene vinylene) with well-defined polystyrene (PPV/PSt) as lateral substituents were investigated via direct pyrolysis mass spectrometry. A slight increase in thermal stability of PSt was detected for (PPV/PSt) and attributed to higher thermal stability of PPV backbone. It was almost impossible to differentiate products due to the decomposition of PPV backbone from those pro...
Direct Pyrolysis - Mass Spectrometry Analysis of Thermal Degradation of Thio-Click-Modified Poly(2-oxazoline) Atilkan, Nurcan; Schlaad, Helmut; NUR, YUSUF; Hacaloğlu, Jale (2014-01-01) Poly(2‐(3‐butenyl)‐2‐oxazoline)s (PBOX) with glucose‐S‐butyl (Glc) and perfluoroalkyl‐S‐butyl (F) side chains (three samples: Glc/F = 100/0, 0/100, and 88/12) are synthesized by ring‐opening polymerization of 2‐butenyl‐2‐oxazoline and thiol‐ene click photochemistry, and their thermal properties are analyzed by direct‐pyrolysis mass spectrometry. Significant changes in the thermal stability and thermal‐degradation products are observed depending on the structure of the side chain. The thermal degradation of ...
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...
Investigation of polymerization of benzoxazines and thermal degradation characteristics of polybenzoxazines via direct pyrolysis mass spectrometry Fam, Shahla Bagheri; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2012-10-01) Polymerization of benzoxazines and thermal degradation mechanisms of polybenzoxazines were investigated using the direct pyrolysis mass spectrometry (DP-MS) technique. The benzoxazine structures were based on phenol and aniline and on bisphenol-A and methylamine or aniline. Polymerizations of the benzoxazines were carried out by curing them at elevated temperatures without addition of initiator or catalyst. DP-MS data showed the presence of chains generated by opposing polymerization reaction pathways indic...
Thermal degradation characteristics of polysulfones with benzoxazine end groups Orhan, Tugba; Ates, Sahin; Hacaloğlu, Jale; Yagci, Yusuf (2012-01-01) 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. The...
