Abstract Metal salts of mono(hydroxyethoxyethyl)phthalate [M(HEEP) 2 ] (M = Ca 2+ , Cd 2+ , and Pb 2+ ) were synthesized by the reaction of diethylene glycol, phthalic anhydride, and metal acetates. A series of metal‐containing polyurethanes (PUs) were synthesized by the reaction of hexamethylene diisocyanate or tolylene 2,4‐diisocyanate with Ca 2+ , Cd 2+ , and Pb 2+ salts of mono(hydroxyethoxyethyl)phthalate using di‐ n ‐butyltin dilaurate as a catalyst. The PUs were well characterized by FTIR, 1 H, and 13 C NMR, solid‐state 13 C‐CP‐MAS NMR, viscosity, solubility, elemental, and X‐ray diffraction studies. Thermal properties of the polymers were also studied by using thermogravimetric analysis and differential scanning calorimetry. The antibacterial activities of these polyurethanes have also been investigated by using the agar diffusion method. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 91: 288–295, 2004
