Electrochemical polymerization of N-vinylcarbazole (NVC) on platinum electrodes was studied. Effects of concentration, electrode area, polymerization potential, and solvent on the polymerization rate were discussed. Insulating and conducting polymers of NVC can be simultaneously prepared depending on the electrolysis conditions. The insulating PNVC cannot only be converted into a conducting one but can also be blended with other conducting polymers such as polythiophene and polypyrrole. Soluble insulating polymers of NVC were characterized by FTIR, NMR, and DSC studies. Conducting polymers were characterized by FTIR and 4-probe conductivity measurements.

Synthesis and Characterization of Conducting Copolymers of Bisphenol A-Diglycidyl Ether with Thiophene Side-Groups and Pyrrole Sahmetlioglu, Ertugrul; Varol, Ramazan; Toppare, Levent Kamil; Yuruk, Huseyin (Informa UK Limited, 2009-01-01) Copolymers of bisphenol A-diglycidyl ether with thiophene side-groups and pyrrole were synthesized by electrochemical polymerization. Bisphenol A-diglycidyl ether with thiophene side-groups (DGEBATh) was obtained from the reaction between bisphenol A-diglycidyl ether (DGEBA) and thiophene-3-acetic acid. The syntheses of copolymers of DGEBATh and pyrrole were achieved electrochemically using three different supporting electrolytes, p-toluene sulfonic acid (PTSA), sodium dodecyl sulfate (SDS) and tetrabutylam...
Degradation of Poly(2-hydroxyethyl methacrylate) Obtained by Radiation in Aqueous Solution Varguen, Elif; Usanmaz, Ali (Informa UK Limited, 2010-01-01) The degradation of poly(hydroxyethyl methacrylate), PHEMA obtained by -radiation induced polymerization of HEMA in aqueous solution, was studied. The polymer was a gel type and insoluble in common organic solvents. The DSC thermogram of the polymer gave a Tg value at 88.2 degrees C and an endothermic peak showed further polymerization or crosslinking at 110-160 degrees C. The degradation observed in TGA was a depolymerization type. However, the FT-IR of TGA fragments showed no monomer, which was degraded fu...
Effect of N-methyl imidazole and dimethyl pyrazole ligands on polymerization of di(2,4,6-trichlorophenolato)Cu(II)/Co(II) complexes in solid state Kisakurek, D (Informa UK Limited, 2004-08-01) Polymerization of 2,4,6-trichlorophenol (TCPH) was achieved through the thermal decomposition of the copper and cobalt complexes of TCPH with N-containing ligands [N-methyl imidazole (NMIz) and 3,5-dimethyl pyrazole (DMPz)). The structural analysis of the complexes was performed by using Fourier transform infrared (FTIR), differential scanning calorimetry (DSC), mass (MS), UV-VIS, diffuse reflectance (DRS) and electron spin resonance (ESR) spectroscopies, magnetic susceptibility balance and elemental analys...
Synthesis of a novel fluorescent and ion sensitive monomer bearing quinoxaline moieties and its electropolymerization Carbas, Buket Bezgin; KIVRAK, Arif; Zora, Metin; Önal, Ahmet Muhtar (Elsevier BV, 2011-05-01) A novel terthienyl based fluorescent polymer bearing pendant quinoxaline moieties directly attached to the 3-positions of the central thiophene ring was synthesized by electrochemical polymerization of 4-((2,5-dithiophen-2-yl)thiophen-3-yl)pyrrolo[1,2-a]quinoxaline (TT-Q). The corresponding polymer was characterized by cyclic voltammetry, FT-IR and UV-vis spectroscopy. The polymer exhibits a reversible redox behavior (Ep(1/2) = 1.05 V) accompanied with a reversible electrochromic behavior; yellowish orange ...
Influence of Zinc Oxide on Thermoplastic Elastomer-Based Composites: Synthesis, Processing, Structural, and Thermal Characterization ÇELEBİ, HANDE; Bayram, Göknur; DOĞAN, AYDIN (Wiley, 2016-08-01) It was aimed to investigate how thermal conductivity and stability properties of synthesized thermoplastic elastomers were influenced by zinc oxide (ZnO) additives which differed in size and surface treatment. ZnO particles were prepared by the homogeneous precipitation method by mixing aqueous solutions of hexamethylenetetramine (HMT) and zinc nitrate. The obtained particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Poly(v...
