“…The polymerization of halogenated phenols from copper(II) complexes with various amine ligands has been studied since 1959. A series of copper complexes with different types of phenols with various amine ligands were decomposed thermally in solution4–13 or in the solid state14–18 or by electro initiation in solution19–34 in order to examine the effect of the method of decomposition, ligand type and position of substituted halogen on the phenol ring on the structure, molecular weight and percentage conversion of the polymeric products. In addition to copper complexes, halogenated phenol complexes with nickel(II)35, 36 and cobalt(II)37 with pyridine as ligand were synthesized and their thermal decomposition in the solid state was investigated.…”

The syntheses of distorted tetrahedral bis(pyridine)bis(trihalophenolato)cobalt(II) complexes from an aqueus solution were achieved and their characterization by FT‐IR, X‐ray, DSC, UV‐visible and elemental analysis in solid state or in melt form is reported. Polymerizations of these complexes were accomplished either at constant temperature, employing different time intervals or constant decomposition times while varying the temperature range. The slow decomposition at constant temperature leads to long chain products, whereas long chains formed at higher temperatures were during a constant time. The resulting poly(dihalophenylene oxide)s were characterized by FT‐IR, 1H NMR, 13C NMR spectral analysis, differential scanning calorimetry and molecular weight determinations by viscometric method. © 2001 Society of Chemical Industry

“…Up to date polymerization of halogenated phenols has been studied with transition and inner transition metal complexes with various amine ligands through various decomposition techniques which are electroinitiation in solution (13), thermal decomposition in solid state (14) and in solution (15 (16). Thus, authors considered the use of N-methylimidazole ligand as a powerful approach to archive better percent conversions.…”

In this study, the synthesis of poly(dibromophenylene oxide)s were achieved via atom transfer radical rearrangement polymerization through decomposition of Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)Cu(II)-Cu(TBP) 2 (NMIZ) 2 , Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)Co(II)-Co(TBP) 2 (NMIZ) 2 , Bis(2,4,6-tribromophenolato)di(N-methyl imidazole)Ni(II)-Ni(TBP) 2 (NMIZ) 2 complexes. Polymerizations were carried out under two different conditions to investigate the effect of time and temperature on percent conversions, intrinsic viscosities. Characterizations of the polymers were performed by FTIR, DSC, 1 H-NMR, 13 C-NMR, SEM and viscometric measurements. The poly(dibromophenylene oxides)s, synthesized by the transition metal complexes, having nonchelating ligand N-methyl imidazole, displayed selectivity in the favor of 1-2 and 1-4 additions, taking place at equal rates irrespective of the type of the metal used. Among the synthesized polymers, the highest percent conversion and intrinsic viscosity was achieved by the decomposition of Cu(TBP) 2 (NMIZ) 2 complex, whereas, Ni(TBP) 2 (NMIZ) 2 yielded the lowest. Investigation of the complexes via mass spectroscopy and the thermal behavior of the by-products enlightened the underlying reasons of the variations at percent conversion and intrinsic viscosity values of the resultant polymeric products.

“…Various decomposition techniques were used, such as electroinitiation and thermal decomposition in solution or in the solid state, or microwave initiation in the solid state [30]. Beside the via free access decomposition methods, the types of the ligands and halogen substituents were effective regarding the structure, molecular weight, intrinsic viscosity and conversion of the polymers.…”

The synthesis of the poly(dichloro-or dibromophenylene oxide)s was achieved by the thermal decomposition of diammine-bis(2,4,6-trihalophenolato)copper(II) complexes in the solid state by atom transfer rearrangement radical polymerization. The thermal decomposition was performed either at different temperature ranges, 110 -250 • C, for 3 h, or at the maximum conversion temperature for different time intervals, 3 -48 h. Maximum yields of polymers were obtained at 190 • C and 3 h. The polymers were characterized by FTIR, 1 H and 13 C NMR spectroscopy, SEM, TGA and molecular weight determination by viscometrical methods. All the polymers were rigid, having high T g values between 178 and 189 • C. Only small amounts of Cu were detected by AAS.
