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 hindrance inhibited the growth of the polymer through 2-position and polymerization proceeded via coupling of thiophene moieties mainly at 5-position yielding a polymer with a lower conductivity

Investigation of polymerization of benzoxazines and thermal degradation characteristics of polybenzoxazines via direct pyrolysis mass spectrometry Fam, Shahla Bagheri; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2012-10-01) Polymerization of benzoxazines and thermal degradation mechanisms of polybenzoxazines were investigated using the direct pyrolysis mass spectrometry (DP-MS) technique. The benzoxazine structures were based on phenol and aniline and on bisphenol-A and methylamine or aniline. Polymerizations of the benzoxazines were carried out by curing them at elevated temperatures without addition of initiator or catalyst. DP-MS data showed the presence of chains generated by opposing polymerization reaction pathways indic...
Characterization of polyaniline via pyrolysis mass spectrometry Hacaloğlu, Jale; Kücükyavuz, Zühal (2008-04-05) In this work, direct insertion probe pyrolysis mass spectrometry technique was applied to investigate the thermal and the structural characteristics of electrochemically prepared HCl and HNO3-doped polyaniline (PANI) films. It has been determined that the thermal degradation of both samples showed three main thermal degradation stages. The first stage around 50-60 degrees C was associated with evolution of solvent and low-molecular-weight species adsorbed on the polymer, the second stage just above 150 degr...
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. ...
The use of pyrolysis mass spectrometry to investigate polymerization and degradation processes of methyl amine-based benzoxazine Bagherifam, Shahla; Uyar, Tamer; Ishida, Hatsuo; Hacaloğlu, Jale (2010-06-01) In this study, direct pyrolysis mass spectrometry, DP-MS, was applied to investigate curing and polymerization mechanisms of phenol and methyl amine-based benzoxazine monomer, and thermal decomposition and crosslinking characteristics of the corresponding polybenzoxazine. The results indicated opposing polymerization reaction routes besides the generally accepted one. The cleavage of C-O bonds of the oxazine rings either followed by transformation into a polymer constituting ortho or para substituted phenol...
A pyrolysis mass spectrometry study of polythiophene copolymers Aslan, Evren; Hacaloğlu, Jale; Toppare, Levent Kamil (2007-05-01) The thermal behaviour of copolymers of thiophene with decanedioic acid bis-(2-thiophen-3-yl-ethyl)ester (DATE) and terephthalic acid his(2-thiophen-3-yl-ethyl)ester (TATE) prepared by potentiostatic polymerization was studied via pyrolysis mass spectrometry. It was determined that the electrolytic films correspond to the related homopolymers. The increase in thermal stability of ester linkages, and evolution of characteristic degradation products of TATE and DATE together with thiophene based products above...
