Özet

In this study the synthesis of poly(dihalophenylene oxides) by the solid state thermal decomposition of a bis (4-chloro-2,6-dibromo phenoxo) ethylenediamine copper (II) complex was achieved. Yields, structures and intrinsic viscosities of the polymers were compared with those of electroinitiated and solution decomposition methods. The characterization of the polymers was carried out using FTIR and H-1-NMR spectroscopies, differential scanning calorimetry and viscosity measurements. Optimum yield was obtained at 140 degrees C for a decomposition time of 24 hr. Polymerization proceeded through 1,2 and 1,4 additions taking place at the same time leading to a branched structure.
