Living bifunctional azo-polytetrahydrofuran (azo-PTHF) was terminated with pyrrolyl potassium salt to yield a polymer with electrochemically active functional end groups. This polymer is further used to synthesize polytetrahydrofuran-polystyrene (PTHF-b-PS-b-PTHF) block copolymer. These polymers are electrochemically blocked with polypyrrole using constant potential electrolysis (PPy/Azo-PTHF and PPy/PTHF-b-PS-b-PTHF). Two different solvent-electrolyte pairs were used during electrolysis. Characterizations of pristine and the blocked copolpolymers are based on Cyclic Voltammetry (CV), Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Thermal Gravimetry Analysis (TGA), Scanning Electron Microscope (SEM) Nuclear Magnetic Resonance Spectroscopy (NMR) and Gel Permeation Chromatography (GPC). Conductivities were measured using a four-probe technique.

Conducting graft copolymers of pyrrole and thiophene with random copolymers of methyl methacrylate and 3-methylthienyl methacrylate Guner, Y; Toppare, Levent Kamil; Hepuzer, Y; Yagci, Y (2004-08-01) Random copolymers of 3-methyl thienylmethacrylate and methyl methacrylate were synthesized via free radical polymerization. Electro-copolymerizations of random copolymers with thiophene and/or pyrrole were carried out in acetonitrile-tetrabutylammonium tetrafluoroborate (TBAFB), water-p-toluene sulfonic acid (PTSA) solvent-electrolyte couples. Oxidative polymerization of thiophene functionalized random copolymer was also achieved by constant current electrolysis and chemical polymerization. The characteriza...
Conducting graft copolymers of poly (3-methylthienyl methacrylate) with pyrrole and thiophene Çırpan, Ali; Toppare, Levent Kamil; YAGCI, Y (2002-12-01) A thiophene-functionalized methacrylate monomer (3-methylthienyl methacrylate) was synthesized via the esterification of 3-thiophene methanol with methacryloyl chloride. The methacrylate monomer was polymerized by free-radical polymerization in the presence of azobisisobutyronitrile as the initiator. Graft copolymers of poly(3-methylthienyl methacrylate) (PMTM2) and polypyrrole and of PMTM2 and polythiophene were synthesized by constant-potential electrolyses. p-Toluene sulfonic acid, sodium dodecyl sulfate...
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...
Synthesis of conducting PPy/pTHF copolymers Kizilyar, N; Toppare, Levent Kamil; Onen, A; Yagci, Y (Wiley, 1999-01-31) Living polytetrahydrofuran (pTHF) was terminated with the potassium salt of pyrrole to yield polymers with pyrrole end groups. Copolymerization of THF and pyrrole with short and long I,THF segments was achieved by constant potential electrolysis. Syntheses of the block copolymers were performed using tetrabutylammonium tetrafluoroborate, sodium pel:chlorate, and sodium p-toluenesulfonate as the supporting electrolytes. Characterization of the block copolymers were based on scanning electron microscopy, diff...
