Abstract
ABSTRACT Divalent metal salts of mono(hydroxybutyl)phthalate were synthesized by the addition of 1,4-butane diol, phthalic anhydride and divalent metal [Ca2+, Mn2+ and Pb2+] acetates. A series of metal containing polyurethane and polyurethane-ureas containing ionic links in the main chain were synthesized by the polyaddition reaction of hexamethylene diisocyanate (HMDI) or toluylene 2,4-diisocyanate (TDI) with divalent metal salts of mono(hydroxybutyl)-phthalate [M(HBP)2] and 1:1 mixtures of toluylene 2,4-bis(ω, N-hydroxyethylurea) [TBHEU] and M(HBP)2. M(HBP)2 and the polymers were characterized by elemental analysis, solubility, viscosity, spectral studies (IR and FT NMR) and thermogravimetric analysis (TGA).
