Thermal behaviors of poly(1,2-epoxy-4-epoxyethylcyclohexanes) (poly-EECH), polymerized by electroinitiation, radiation, and catalytic action of HClO4 and BF3-etharate, have been studied by direct pyrolysis MS and evolved gas analyses by mass and FT-IR spectrometric techniques. Direct pyrolysis experiments indicated that electroinitiated and catalytic polymerization of EECH with the use of BF3-etharate produced the least stable polymers thermally. High mass peaks were related to the presence of blocks propagated through the 1,2-epoxy group, especially in the polymer produced by catalytic action of BF3-etharate. Crosslinked structures were also justified by thermal analysis. Production of low molecular weight compounds such as CO, CO2, CH3OH, ethylene oxide, methylpropionate, and cyclohexane was investigated by evolved gas analysis.

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...
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...
Polylactide/organically modified montmorillonite composites; effects of organic modifier on thermal characteristics
Ozdemir, Esra; Öztürk, Yurdagül; Hacaloğlu, Jale (2016-12-01)
The effects of interspace distance and the possible chemical interactions between PLA and the organic modifier of montmorillonites, Cloisite 15A, 20A and 30B on thermal degradation of PLA in the absence and presence of water vapor were investigated by direct pyrolysis mass spectrometry, (DP-MS) in addition to XRD, TEM, DSC, TGA analyses. The DP-MS results clearly showed that the way in which the polymer was incorporated into the nanocomposite strongly depends on the mixing technique, the interspacing betwee...
Pyrolysis of of poly(methy methacrylate) copolymers
Ozlem-Gundogdu, Suriye; Gurel, Evren Aslan; Hacaloğlu, Jale (2015-05-01)
In this work, thermal degradation of copolymers of poly(methy methacrylate) namely, poly(methyl methacrylate-co-n-butyl acrylate), P(MMA-co-nBu), poly(methyl methacrylate-co-n-benzyl methacrylate) P(MMA-co-BzMA, and poly(methyl methacrylate-co-isobornyl acrylate), P(MMA-co-IBA) were investigated via direct pyrolysis mass spectrometry. It was determined that whether an available gamma-H with respect to the carbonyl groups is present or not determines the thermal degradation mechanisms of polyacrylates and po...
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...
