CommunicationPoly(Urethane-Urea)s: Part 2Gujarat Narmada Valley Fertilizers Co. Ltd, Narmadanagar - 392 015, Dist. Bharuch, Gujarat, India
Department of Chemistry, South Gujarat University, Surat, Gujarat, India
Department of Chemistry, Sardar Patel University, Vallabh Vidyanagar, Guj, India Four various poly(urethane-urea)s (PUUs) were prepared by polycondensation of 3-aminophenol with various diisocyanates. The resultant poly(urethane-urea)s were characterized by elemental analyses, IR spectral studies, number average molecular weight (Mn) estimated by non-aqueous conductometric titration and thermogravimetry. The electrical properties of these polymers have also been measured at room temperature.
