SYNTHESIS AND CHARACTERIZATION OF POLY(DICHLOROPHENYLENE OXIDE)S THROUGH SOLID-STATE THERMAL-DECOMPOSITION OF BIS(PYRIDINE)BIS(TRICHLOROPHENOXO)COPPER(II) COMPLEXES

Thermal polymerization of bis(pyridine)bis(trichlorophenoxo)copper(II) was achieved in the solid state for the first time. The time and temperature effect on polymer molecular weight, percentage yield and the structure of polymer was first studied, at constant temperature and then for constant decomposition time. Polymers were characterized by i.r., H-1 n.m.r. and C-13 n.m.r. The molecular weights of the polymers were obtained by viscometric measurements at 30-degrees-C in toluene and glass transition temperatures were obtained by d.s.c.

Ünal, H. Ibrahim; Kısakürek, Duygu; Şanlı, Oya (Elsevier BV, 1989-2)
Thermal polymerization of bis(trihalophenoxo)-N,N,N′,N′-tetramethylethylenediamine copper(ii) and bis(trihalophenoxo)ethylenediamine copper(ii) was achieved in toluene at 70°C. The dependences of intrinsic viscosity and the percentage yield of the polymers on a sequence of increasing decomposition times of copper complexes were investigated. Structural analyses of the polymers were carried out using mainly1H nuclear magnetic resonance spectroscopy and differential scanning calorimetry. 1,4-Catenation was hi...

Yiğit, S.; Kısakürek, D.; Türker, L; Toppare, Levent Kamil; Akbulut, Ural (Elsevier BV, 1989-02-01)
Electroinitiated polymerization of bis(trichlorophenoxo) ethylenediamine copper (II) complex was carried out in dimethyl-formamide at various anodic peak potentials of the complex. The oxidation and reduction peak potentials were determined by cyclic voltammetry. These potentials were measured in tetrabutylammonium fluoroborate-dimethylformamide supporting electrolyte-solvent couple at room temperature. Polymerization reactions were carried out under air and nitrogen atmospheres using a constant potential a...

SACAK, M; Akbulut, Ural; KISAKUREK, D; TURKER, L; Toppare, Levent Kamil (Wiley, 1989-04-01)
Electroninitiated polymerization of bis(trichlorophenoxo)‐N,N,N′,N′‐tetramethylethylene diamine copper(II) was achieved in acetonitrile at various peak potentials of the monomer. A constant potential approach was selected in polymerization reactions. Electrolyses were carried out under air, nitrogen, and oxygen atmospheres. Structural analyses of the polymers were done by 1H‐NMR and 13C‐NMR FT–IR spectroscopy. Molecular weights of the polymers were determined by vapor pressure (isopiestic) method.
Synthesis and Characterization of a New Conducting Polymer Based on 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-phthalonitrile
Yavuz, Arzu; Bezgin, Buket; Önal, Ahmet Muhtar (Wiley, 2009-12-05)
A new conducting polymer was synthesized by electrochemical polymerization of 4-(2,5-di-2-thiophen-2-yl-pyrrol-1-yl)-2-phthalonitrile (SNS-PN). Electrochemical polymerization of SNS-PN was performed in acetonitrile/0.2M LiClO4 solvent/electrolyte couple. Characterizations of the resulting polymer P(SNS-PN) were carried out by cyclic voltammetry, UV-vis, and Fourier transform infrared (FTIR) spectroscopic techniques. Spectroelectrochemical studies revealed that P(SNS-PN) has an electronic band gap of 2.45 eV...
Synthesis, crosslinking, and characterization of energetic polymers through the azidification of glycidyl ether prepolymers
Kara, S; Ozturk, E; Polat, K; Alyuruk, K (Wiley, 2004-03-15)
Low-molecular-weight atactic poly(propylene oxide) and poly(epichlorohydrin) (PECH) were chlorinated on average up to 4.42 chlorine atoms per repeat unit. A study of the products showed that chlorine substitution preferentially occurred on already chlorinated repeat units, yielding chlorine -rich and chlorine -poor sequences. As the extent of chlorine substitution increased, the glass-transition temperature of the polymers markedly increased, and their solubility in most of the organic solvents drastically ...
