    • Abstract

       

      Poly [azo(6-hydroxy-1,3-phenylene)] (PAHP) was prepared by alcoholic alkaline reduction of 2,4-dinitro phenol (DNP). The polymers prepared at various time intervals were characterized by elemental analyses, IR spectra and thermogravimetric analysis. The number average molecular weight$$(\bar M_n )$$ was determined by non-aqueous titration. Viscometric study in DMF of all the three polymers were carried out and indicates polyelectrolyte behaviour. Viscometric study in DMF-water (85:15)(v/v) containing 1%KBr shows normal behaviour.

      Polymeric metal chelates of Cu2+, Ni2+, Co2+, Zn2+, Mn2+ and Cr2+ with PAHP polymer were prepared and characterized.
