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 tetrabutylammonium tetrafluoroborate (TBAFB). Characterizations of DGEBATh and copolymers were performed by combination of techniques including cyclic voltammetry, scanning electron microscopy, gel permeation chromatography, differential scanning calorimetry, 1H-NMR and FT-IR. The conductivities were measured by the four-probe technique.

Synthesis, characterization and electrochromic properties of copolymer of terephthalic acid bis-(thiophen-3-yl-methyl) thioester with thiophene
Turkarslan, O; Erden, A; Sahin, E; Toppare, Levent Kamil (Informa UK Limited, 2006-01-01)
Terephthalic acid bis-(thiophen-3-yl-methyl thioester) (TTMT) was synthesized via the reaction of thiophen-3-yl methanethiol with terephthaloyl dichloride. Nuclear magnetic resonance ( H-1-NMR) spectroscopy and Fourier transform infrared (FTIR) spectroscopy were utilized for the characterization of the monomer. Electrochemical copolymerization of TTMT with thiophene in acetonitrile/boron trifluoride diethyl etherate (AN/BFEE) (8:2, v/v) solvent mixture was realized by using tetrabutylammonium tetrafluorobor...

2-[(3-Thienylcarbonyl)oxy]ethyl 3-thiophene carboxylate (TOET) was synthesized via the reaction of 3-thionylcarboxylic acid with ethylene glycol, and electrochemically polymerized with thiophene (Th) and pyrrole (Py) by using tetrabutylannnonium tetrafluoroborate (TBAFB) as the supporting electrolyte in acetonitrile (ACN). Characterization of the resulting copolymers were performed via cyclic voltammetry, FTIR, and scanning electron microscopy (SEM). Electrical conductivities are measured by the four-probe ...
Synthesis and mesophase properties of block and random co-polymers of electroactive and liquid crystalline monomers
Yilmaz, F; Kasapoglu, F; Hepuzer, Y; Yagci, Y; Toppare, Levent Kamil; Fernandes, EG; Galli, G (Informa UK Limited, 2005-01-01)
Homo-polymers and random co-polymers of electroactive and liquid crystalline monomers, namely 3-thienylmethyl methacrylate (MTM) and 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (LC6), were prepared by conventional free radical polymerization. Block co-polymers of MTM and LC6 were also synthesized by using the 1,1-diphenylethene (DPE) method. The obtained random and block co-polymers exhibited liquid crystal behavior depending on the content of the LC6 units. It was found that microphase separation of the polym...
Preparation of a conducting flexible material from silane coupling agent and hydroxyl terminated polybutadiene rubber by hydrolysis and condensation
Karatas, Y; Toppare, Levent Kamil; Tincer, T (Informa UK Limited, 2003-01-01)
Synthesis and characterization of a flexible polymer produced from silane coupling agent (SCA) and hydroxyl terminated polybutadiene (HTPB) were performed. Mechanical properties of chemically and electrochemically prepared conducting composites synthesized from this polymer were investigated. Conductivities of the composites were also measured. Polypyrrole enhanced the mechanical properties of the chemically prepared conducting composite. Doping with iodine greatly changed the conductivity of the composite....
Synthesis and properties of thermotropic liquid crystalline copolyesters containing p-hydroxyphenylacetic acid and m-hydroxybenzoic acid units
Yerlikaya, Z; Aksoy, S; Bayramlı, Erdal (Informa UK Limited, 2006-03-01)
A series of copolyesters based on p-acetoxybenzoic acid (p-ABA), m-acetoxybenzoic acid (m-ABA), and p-acetoxyphenylacetic acid (p-APAA) were prepared by a modified melt polycondensation reaction. The effect of linear p-ABA structure, kink m-ABA and flexible p-APAA moiety on the properties of copolyesters were systematically investigated. The copolyesters were characterized by DSC, thermogravimetric analysis, 1 H-NMR, polarized optical microscopy, X-ray diffraction, and intrinsic viscosity measurements. The ...
