The thermal degradation processes of p-toluene sulfonate (PTS) doped polypyrrole (PPY) grown from the pyrrole moiety located at both the ends of polytetrahydrofuran (PTHF) have been studied by direct pyrolysis mass spectrometry (DPMS) to gain structural information. To get a better insight, pyrolysis analysis on corresponding homopolymers, PTHF and PPY, have also been carried out. The DPMS data were in accordance with TGA results indicating a significant decrease in thermal stability of the copolymer with respect to both PPY and the matrix polymers. The data also pointed out the degradation of matrix polymer, PTHF during the electrochemical synthesis of polypyrrole on a PTHF coated anode. Although decomposition of matrix polymer occurred, the growth of pyrrole from the pyrrole moieties located at chain ends of PTHF was also confirmed. Thus, it has been proved that a low molecular weight copolymer of polypyrrole involving short chains of PTHF as the end groups has been synthesized.

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...
Investigation of copolymers of thiophene-functionalized polystyrene with pyrrole by pyrolysis mass spectrometry
Papila, Ozge; Toppare, Levent Kamil; Hacaloğlu, Jale (2006-06-01)
The thermal and structural characterization of electrochemically synthesized thiophene-functionalized polystyrene and pyrrole (PS/PPy) and their copolymers were investigated by direct pyrolysis mass spectrometry. The pyrolysis data confirmed the growth of polypyrrole onto the pendant thiophene moiety of polystyrene. It is determined that the electrolytic film has different properties from the mechanical mixture and the related homopolymers.
Characterization of conducting copolymer of pyrrole via pyrolysis mass spectrometry
Levent, Anil; Hacaloğlu, Jale; Toppare, Levent Kamil (2008-03-01)
In this work, structural and thermal characterization of BF4- doped copolymer of pyrrole (PPy) with 2-methylbutyl-2-(3-thienyl)acetate prepared by electrochemical polymerization were performed via a pyrolysis mass spectrometry technique. The pyrolysis mass spectrometry data of the copolymer PPy/PMBTA, and the homopolymers; polypyrrole, PPy, and poly(2-methylbutyl-2-(3-thienyl)acetate), PMBTA were analyzed and compared. It has been determined that when the electrochemical polymerization of pyrrole was achiev...
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 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...
