Poly(8‐hydroxyquinoline‐furfural) (8HQ‐Fu) was prepared by condensing 8‐hydroxyquinoline with furfural in the presence of aqueous K2CO3 and NaOH as catalysts using equimolar proportions of the two reactants. The polymer samples were characterized by elemental analysis, IR spectra, and thermogravimetric analysis. The number average molecular weight (Mn) was determined both by vapour pressure osmometry and by non‐aqueous titration. Intrinsic viscosities of all the polymer samples were measured in DMF. Polymeric metal chelates of Cu2+, Fe3+, Co2+, Zn2+, Mn2+, Ni2+ with the 8HQ‐Fu polymer were prepared and characterized.
