Abstract
Acid catalyzed phenol-formaldehyde (PF) i.e. novolac resin was prepared by established method and then it was treated with succinic anhydride. The resultant oligomeric ligand called phthalated novolac designated as SPH-PF and was characterized by elemental and spectral analysis. The oligomeric metal chalets of SPH-PF with Cu2+, Co2+ , Ni2+, Mn2+ and Zn2+ metal ions were prepared and studied for their metal:ligand (M:L), stoichiometry, magnetic moment, spectral features, number-average molecular weight(Mn ) and by thermogravimetry
