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 achieved on PMBTA coated anode through the thiophene moieties of PMBTA, characteristics of both PTh and PMBTA were retained to a certin extent. However, when thiophene was polymerized in the presence of MBTA, a polymer film with lower conductivity, but more uniform structure, was produced.

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 conducting copolymers of succinic acid bis-(-4-pyrrol-1-yl-phenyl) ester and thiophene via pyrolysis mass spectrometry Ertas, Merve; Hacaloğlu, Jale; Toppare, Levent Kamil (2005-03-01) 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. ...
Characterization of BF4- doped polythiophene via pyrolysis mass spectrometry Gozet, T.; Önal, Ahmet Muhtar; Hacaloğlu, Jale (2003-04-04) In this work, electrochemically polymerizated polythiophene have been characterized by direct pyrolysis MS and Curie point pyrolysis GCMS techniques. The effect of doping level and type of the dopant on thermal characteristics and decomposition products of polythiophene have been investigated. It has been determined that the thermal degradation of polythiophene occurs in two steps, the first being the loss of the dopant, and the second being the degradation of the polymer main chain. The temperature range a...
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 ...
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.
