The synthesis of poly(dihalophenylene oxide)s by solid‐state thermal decomposition of manganese phenolate complexes with ethylenediamine ligand was achieved. The complexes were characterized by infrared (IR) spectroscopy and C, H, N elemental analysis. The dependence of the yield of polymers on temperature and decomposition time of the manganese complexes with 2,4,6‐trichlorophenol, 2,4,6‐tribromophenol and 2,6‐dibromo‐4‐chlorophenol was investigated. The polymers obtained were characterized by 1 H NMR, IR spectroscopy and differential scanning calorimetry and found to be branched. 1,2‐Catenation is favoured over 1,4‐addition in 2,4,6‐tribromophenoxide and 2,6‐dibromo‐4‐chlorophenoxide derived polymers, however, polymers synthesized from trichlorophenolate display a selectivity in favour of 1,2‐catenation.
