SYNTHESIS AND CHARACTERIZATION OF POLY(DICHLOROPHENYLENE OXIDE)S THROUGH SOLID-STATE THERMAL-DECOMPOSITION OF BIS(PYRIDINE)BIS(TRICHLOROPHENOXO)COPPER(II) COMPLEXES BASTURKMEN, M; KISAKUREK, D (Elsevier BV, 1993-01-01) 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 tempe...
Synthesis and characterization of poly(dihalophenylene oxides) by thermal decomposition of copper complexes with tetramethylethylenediamine and ethylenediamine ligands 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...

SYNTHESIS AND CHARACTERIZATION OF POLY(DICHLOROPHENYLENE OXIDE)S BASED ON THE ELECTROOXIDATION OF BIS(2,4,6-TRICHLOROPHENOXO)BIS(PYRIDINE)COPPER(II) COMPLEX SEN, S; KISAKUREK, D (Elsevier BV, 1993-01-01) Electroinitiated polymerization of bis(2,4,6-trichlorophenoxo)bis(pyridine)copper(II) complex was achieved in dimethylformamide by constant potential electrolysis under air and N2. The polymers obtained at several potentials were characterized by H-1 n.m.r., C-13 n.m.r., FTi.r. and d.s.c., and were found to be branched. The kinetics of the polymerization were followed by in situ cyclic voltammetry measurements at 13.5 and 20-degrees-C during electrolysis. As found for the thermal polymerization of this comp...
