Metal salts of mono(hydroxypentyl)phthalate [M(HPP) 2 , where M is Ca 2ϩ , Cd 2ϩ , Pb 2ϩ , or Zn 2ϩ ] were synthesized by the reaction of 1,5-pentane diol, phthalic anhydride, and metal acetate. A new series of metal-containing polyurethanes containing ionic links in the main chain were synthesized by the reaction of hexamethylene diisocyanate or toluylene 2,4-diisocyanate with the M(HPP) 2 salts. The structures of the monomers and polymers were confirmed with infrared, 1 H-NMR, and 13 C-NMR spectra and elemental analysis. The polymers were also characterized with thermogravimetric analysis, differential scanning calorimetry, and solubility and viscosity measurements. The antibacterial activity of these polyurethanes was investigated with the agar diffusion method.
Metal salts of mono(hydroxyethoxyethyl)phthalate [M(HEEP) 2 ] (M ϭ Ca 2ϩ , Cd 2ϩ , and Pb 2ϩ ) 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 2ϩ , Cd 2ϩ , and Pb 2ϩ 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
