Synthesis and characterization of metal-containing polyurethanes and polyurethane-ureas

Metal-containing polyurethanes containing ionic linkages in the main chain were synthesized by the polyaddition reaction of hexamethylene diisocyanate (HMDI) or toluylene 2,4-diisocyanate (TDI) with 1:1 mixtures of divalent m etal salts of mono (hydroxybutyl)phthalate [M(HBP)(2)] and digol [DG]. Simi larly polyurethane-ureas were synthesized by reacting the diisocyanates wit h 1:1 mixtures of hexamethylene bis(omega,N-hydroxyethyl-urea) (HBHEU) and M(HBP)2. The polymers were characterized by elemental analysis, thermogravi metric analysis, solubility, visocity and spectral studies. (C) 1999 Elsevi er Science Ltd. All rights reserved.
