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 ...
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 of Polylactide and Its Electrospun Fiber
Ozdemir, Esra; Hacaloğlu, Jale (2016-01-01)
Thermal degradations of poly(lactic acid), (PLA) and its fiber were studied via direct pyrolysis mass spectrometry. As the amount of PLA pyrolyzed was increased the relative yields of protonated and cyclic oligomers were increased indicating that inter-molecular interactions were promoted. Hydrolysis reactions caused significant decrease in the relative yields of high mass products. Intermolecular trans-esterifications were more effective during the pyrolysis of PLA fiber. On the other hand, PLA fiber showe...
