Investigation of copolymers of thiophene-functionalized polystyrene with pyrrole by pyrolysis mass spectrometry

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.

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...
Direct pyrolysis mass spectrometry to investigate the effects of dopants on characteristics of polypyrrole and its copolymers
Guerel, Evren Aslan; Toppare, Levent Kamil; Hacaloğlu, Jale (2013-02-01)
Polypyrrole and its copolymers with terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester, (P(TATE-co-Py) were characterized by direct pyrolysis mass spectrometry to investigate the effects of dopant on thermal stability and conductivity. Conductivities of the films were measured with four-probe technique, and the results were compared with the pyrolysis data. In general, an increase in conductivity was detected as the stability of dopant increased. The extent of doping and the strength of interaction between t...
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...
Structural and thermal characterization of PTSA doped polypyrrole-polytetrahydrofuran graft copolymer
Özdilek, Ceren; Hacaloğlu, Jale; Toppare, Levent Kamil; Yagč, Yusuf (2004-01-06)
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 r...

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...
