Abstract:Polyol having a molecular weight of 1825 was prepared with the reaction of 5-Sulfoisophthalic acid monosodium salt,adipic acid and 1,6-dexanediol.A prepolymer was prepared by reacting the obtained polyol with isophorone diisocyanate,1,4-butanediol and 2,2-dimethylolpropionic acid.The prepolymer was dispersed under vigorous agitation by adding water and extended by adding ethylenediamine.Finally the waterbased polyurethane having high molecular weight and white paste-like was obtained.The obtained polyol and polyurethane were characterized by means of IR spectra, 1H NMR spectra,DSC and WAXD.
Keywords:polyo1  waterbased polyurethane  solvent-free
