摘要：

Zinc containing poly(urethane-urea)s having ionic links in the main chain were synthesized by the reaction of hexamethylene diisocyanate or tolyiene-2,4-diisocyanate with 1:1 mixture of zinc salt of mono(hydroxyethoxyethyl) phthalate and each of the bisureas such as hexamethylene-bis(omega,N-hydroxyethylurea), tolylene-2,4,-bis(omega,N-hydroxyethylurea), hexamethylene-bis(omega,N-hydroxypropylurea) and tolylene-2,4-bis(omega,N-hydroxypropylurea) using di-n-butyltin dilaurate as catalyst. These polymers were characterized by FT-IR, H-1 NMR and C-13 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. (C) 2003 Elsevier B.V. All rights reserved.
