This article reports the direct pyrolysis mass spectrometry results on p-toluene sulfonate doped polypyrrole synthesized through the thiophene moities of thiophene-capped poly(methyl methacrylate), TPMMA. Pyrolysis data gave strong evidence for decomposition of the matrix polymer TPMMA during the electrochemical polymerization of pyrrole with a TPMMA coated anode. However, evolution of products diagnostic of TPMMA around 370°C, the temperature region of PPY degradation, and presence of fragments involving both thiophene and pyrrole units confirmed the growth of polypyrrole from the end groups of the matrix polymer while the main chain dissociates.

Characterization of doped polypyrrole-poly(methylthienyl methacrylate) films via pyrolysis mass spectrometry
Athar, Imran; Hacaloğlu, Jale; Toppare, Levent Kamil (2004-07-01)
This work presents the characterization of p-toluene sulfonate doped polypyrrole-poly(methylthienyl methacrylate) films synthesized by electrochemical polymerization of pyrrole on a poly(methylthienyl methacrylate) coated anode. Pyrolysis mass spectrometry was used to characterize the polymer. The study was focused on the influence of each of the components on the thermal degradation behaviour of the other. The results indicated that decomposition of the matrix polymer, ie poly(methylthienyl methacrylate), ...
Characterization of polypyrrole/polytetrahydrofuran graft copolymers by direct pyrolysis mass spectrometry
Özdilek, Ceren; Toppare, Levent Kamil; Yagci, Yusuf; Hacaloğlu, Jale (2002-01-01)
The thermal decomposition pathways and products of pyrrole ended-polytetrahydrofuran (PTHF), p-toluene sulfonate doped polypyrrole (PTS-PPY) and polypyrrole/polytetrahydrofuran (PTS-PPY/PTHF) graft copolymers have been investigated by direct pyrolysis mass spectrometry (DPMS). The data suggest that PTHF degrade via mixed random cleavage and unzipping mechanism followed by hydrogen transfer reactions. Decomposition of dopant in the high temperature range is attributed to a strong interaction between the dopa...
Characterization of electrochemically synthesized p-toluene sulfonic acid doped polypyrrole by direct insertion probe pyrolysis mass spectrometry
Uyar, Tamer; Toppare, Levent Kamil; Hacaloğlu, Jale (2002-01-01)
A direct insertion probe pyrolysis mass spectrometry technique was used to perform a systematic thermal characterization of conducting polypyrrole doped with p-toluene sulfonic acid. The effect of dopant concentration on thermal stability and degradation products was investigated using undoped and dedoped polypyrrole samples. The data indicate that polymerization of pyrrole in the absence of dopant produces an aromatic structure, which transforms into the quinoid form at high dopant concentrations. Reductio...
Characterization of polylactide/poly(ethylene glycol) blends via direct pyrolysis mass spectrometry
Ozdemir, Esra; Tincer, Teoman; Hacaloğlu, Jale (2016-11-01)
In this study, melt blended poly(lactic acid) and poly(ethylene glycol), (PLA)/PEG samples involving 10, 15 and 20 wt% PEG were prepared and characterized by direct pyrolysis mass spectrometry technique in addition to classical techniques such differential scanning calorimetry, thermogravimetric analyses and mechanical tests. The incorporation of PEG resulted in consistent and significant decrease in the tensile strength and modulus, and reduction in endothermic melting peak of PLA due to the plasticizing e...
Synthesis of topoisomerase inhibitor type anticancer drugs linked gold nanoparticles
Pekçağlıyan, Gönül; Demir, Ayhan Sıtkı; Department of Chemistry (2008)
This study presents studies on camptothecin (CPT), a potent antitumor agent in order to improve its stability and solubility without reducing its activity. The work describes the modification of camptothecin at 20-OH position a new strategy to overcome the stability and solubility problems of the free drug. Camptothecin is conneted to linker that could be processed to a terminal thiol group and this thiol group was connected to gold surface, to obtain CPT-gold nanoparticles. In the first part of the study; ...
