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 v

## Abstract Polysulfone has been carboxylated, via a metalated intermediate, by reaction of a THF solution of polymer with __n__โbutyllithium and then treatment with carbon dioxide. The polymer reactions with __n__โbutyllithium were close to quantitative and did not require the use of a tertiary am

A series of novel carboxyl telechelic microspheres (CTMs) with different length of oligo-caprolactone telechelic chains are readily prepared via a three-step approach involving: (1) the hydrolytic oligomerization of 1-caprolactone, (2) the esterification of oligo-caprolactone with maleic anhydride,
