Abstract Number of terpolymers (BPHDF) has been synthesized using the monomers 2, 2’-biphenol, hexamethylene diamine and formaldehyde in the presence of 2M HCl as a catalyst with varying molar proportion of reacting monomers. The purity of newly synthesized resin has been tested and confirmed by the thin layer chromatography (TLC) technique. The number average molecular weight of these terpolymers has been determined by conductometric titration in nonaqueous medium. Viscometric measurements in dimethylformamide have been carried out with a view to ascertain the characteristic functions and constants. Elemental analysis confirms the stoichiometry of the BPHDF terpolymers whereas the structure has been elucidated on the basis of Ultraviolet–visible, Fourier transform Infrared spectroscopy and nuclear magnetic spectroscopic methods. The antibacterial activities of the terpolymers were screened on various pathogenic bacteria viz. Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. Agar diffusion method has been used for antibacterial analysis. Zone of inhibition and activity index with respect to standard antibacterial drug (ciprofloxacin) were measured. All the synthesized polymers have shown excellent antibacterial activities as compared to the standard Ciprofloxacin. Molecular weights and intrinsic viscosities were observed in the range 2896 -15880 and 0.0660 - 0.1077 respectively.
