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 PBOX‐Glc and PBOX‐F homopolymers starts with loss of side chains at relatively low temperatures and successive cleavage along the side and main chains follows. The stability of the glucose units of the PBOX‐Glc/F copolymer is significantly increased by the presence of perfluoroalkyl groups, attributable to OH···F hydrogen bonding interactions during pyrolysis.

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 insertion mass spectrometric analysis of thermal degradation of poly(2-alkyl-2-oxazoline) Atilkan, Nurcan; Nur, Yusuf; Hacaloğlu, Jale; Schlaad, Helmut (2012-05-14) 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 the...
Thermal degradation of poly(p-phenylene-graft-ε-caprolactone) copolymer Nur, Yusuf; Yurteri, Seda; Cianga, Ioan; Yagci, Yusuf; Hacaloğlu, Jale (2007-01-01) The thermal degradation of poly (p-phenylene-graft-epsilon-caprolactone) (PPP), synthesized by Suzuki polycondensation of poly(E-caprolactone) (PCL) with a central 2,5-dibromo-1,4-benzene on the chain with 1,4-phenylene-diboronic acid, has been studied via direct pyrolysis mass spectrometry. The thermal degradation occurred mainly in two steps. In the first step, decomposition of PCL chains occurred. A slight increase in thermal stability of PCL chains was noted. In the second stage of pyrolysis, the decomp...
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...
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...
