In this work, a direct pyrolysis mass spectrometry technique was applied to characterize a conducting copolymer of succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) and thiophene prepared by electrochemical polymerization. Thermal degradation behavior of both components was quite similar to those of the corresponding homopolymers, PSM, and polythiophene PTh. Yet, detection of oligomers and mixed dimers of both monomers in the high temperature pyrolysis mass spectra confirmed the formation of a copolymer. Furthermore, evolution of SM monomer in the temperature range where the fragments, due to the thermal degradation of PTh chains, have been detected. Also, the generation of dimer of thiophene in the temperature range, where the fragments associated with PSM have been observed, pointed out the presence of thiophene and SM units along the PTh and PSM chains. However, as thermal stabilities of PTh and PSM chains were nearly identical to the corresponding homopolymers, it may be concluded that the presence of other monomer or low molecular weight oligomers along the chains of each component did not significantly affect the thermal characteristics.

Characterization of the polymer of a dipyrrolyl monomer by pyrolysis mass spectrometry Ertas, Merve; Hacaloğlu, Jale; Toppare, Levent Kamil (2004-08-01) In this work, characterization of a homopolymer of succinic acid bis(4-pyrrol-1-ylphenyl) ester prepared by galvonastatic polymerization was carried out by direct pyrolysis mass spectrometry. Although decomposition of the monomer yielding mainly butadionic acid and pyrrole occurred under the galvonastatic polymerization conditions, growth of the polymer through the pyrrole moieties was also achieved, yielding a ladder-type polymer film. The polypyrrole chains contained both quinoid and aromatic units as in ...
Characterization of conducting copolymer of thiophene via pyrolysis mass spectrometry Levent, Anil; Hacaloğlu, Jale; Toppare, Levent Kamil (2005-12-01) In this work, structural and thermal characterization of a conducting copolymer of thiophene (PTh) with 2-methylbutyl-2-(3-thienyl)acetate prepared by two different methods has been performed by pyrolysis mass spectrometry techniques. The pyrolysis mass spectrometry data of both components of the copolymer, polythiophene, PTh, poly(2-methylbutyl-2-(3-thienyl)acetate), PMBTA and PTh/PMBTA have been analyzed and compared. It has been determined that when the electrochemical polymerization of thiophene was ach...
Investigation of the effect of substituent on the growth of polymer for 3-substituted polythiophenes via pyrolysis mass spectrometry Aslan, Evren; Toppare, Levent Kamil; Hacaloğlu, Jale (2005-10-15) In this study, direct pyrolysis mass spectrometry analyses of electrochemically polymerized poly(decanedioic acid bis-(2-thiophen-3-yl-ethyl)ester) and poly(terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester) were per-formed to investigate structural and thermal characteristics. It was found that when the ester linkages contain hydrocarbon chains, the growth of polymer occurred through both 2- and 5-positions. On the other hand, when the ester linkages contain more rigid groups such as phenyl, steric hindran...
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 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...
