摘要：

The first direct synthesis of a carboxylated polyurethane is described. The polyurethane, of the segmented type, was obtained by reaction of 4,4'-diphenylmethane diisocyanate with poly(propylene oxide) and the tributylammonium salt of dihydroxymethylpropionic acid. The polymer was characterized by viscometry, DSC, i.r. and NMR spectroscopy. The reactivity of the free carboxylic group in the polymer was evaluated for esterification and amidation.
