Disclosed is a method for production of polyphenylene by means of polymerization of phenols. The method comprises using hydroquinone as a phenol, which is predissolved in water or in alcoholic solution, adding hydrogen peroxide in the presence of transition metals aquo-ions, and controlling temperature during polymerization keeping it not higher than the boiling point, and controlling pH in the range of 2-7. In on example embodiment, Cr, Mn, Fe, Cu, Ni, Co, Zn aquo-ions or a combination thereof may be used as transition metal aquo-ions.
