Antimicrobial,thermoanalytical and viscometric studies of metal based schiff base polymer

This study examines the synthesis,characterization,viscosity,thermal behavior and antimicrobial studies of copper(ii) and nickel(ii),complexes of a synthesized monomer 5,5-methylene bis(2'-pyridinecarboxaldehyde) (mbpc) and a schiff base polymer poly-5,5-methylene bis (2-pyridinecarboxaldehyde) 1,3-propylenedimine (pmbpcpr). the monomer,polymeric ligand and poly metal complexes (pmbpcprcu) and (pmbpcprni) were characterized by c.h.n analysis,ft-ir,uv -vis spectroscopy,viscometery thermogravimetric (tga) and differential thermogravimetry (dta). the monomer mbpc was prepared by the reaction of 2- pyridinecarboxaldehyde with 1,3,5-trioxane in the presence of acetic acid and sulphuric acid. the polymeric ligand was prepared by polycondensation of monomer with 1,3-propylenediamine. the biological studies of compounds revealed that they possessed significant antibacterial and antifungal properties,against micrococcus flavus,staphylococcus aureus,bacillus cirroflgellosus,shigella flexneri,escherichia coli,candida albicans,aspergillus flavus,and a. niger.
