Abstract : Zinc containing poly(urethane–urea)s having ionic links in the main chain were synthesized by the reaction of hexamethylene diisocyanate or tolylene-2,4-diisocyanate with 1:1 mixture of zinc salt of mono(hydroxyethoxyethyl) phthalate and each of the bisureas such as hexamethylene-bis(ω,N-hydroxyethylurea), tolylene-2,4,-bis(ω,N-hydroxyethylurea), hexamethylene-bis(ω,N-hydroxypropylurea) and tolylene–2,4-bis(ω,N-hydroxypropylurea) using di-n-butyltin dilaurate as catalyst. These polymers were characterized by FT-IR, 1H NMR and 13C NMR spectroscopy, elemental analysis, solubility test, viscosity measurement and X-ray diffraction analysis. Thermal properties of the polymers were determined by differential scanning calorimetry and thermogravimetric analysis.
