Abstract : Zinc salt of mono(hydroxypentyl)phthalate [Zn[HPP]2] was synthesized by reacting 1,5-pentane diol, phthalic anhydride and zinc acetate. Zinc containing polyurethanes having ionic linkages in the main chain were synthesized by the polyaddition reaction of hexamethylene diisocyanate (HMDI) or toluylene 2,4-diisocyanate (TDI) with Zn[HPP]2, using di-n-butyltin dilaurate (DBTDL) as catalyst. Four different bisureas were prepared by reacting ethanolamine or propanolamine with HMDI or TDI. Zinc containing polyurethane-ureas were synthesized by reacting HMDI or TDI with 1:1 mixtures of Zn[HPP]2 and each of the bisureas. Zn[HPP]2 and the polymers were characterized by solubility, viscosity study, elemental analysis, FT-IR,1H-NMR,13C-NMR spectroscopy and thermogravimetric analysis (TGA).
