Abstract Novel linear diol 2, diacid 3, and diisocyanate 4 with functional groups located at each end of the chain have been produced from oleic acid via a diester precursor. All the compounds were fully characterized by IR, 1 H NMR, 13 C NMR and Mass Spectrometry. These unbranched terminally-functionalized compounds are important monomers for the manufacture of biodegradable thermoplastic polyurethanes and polyesters. The general ...
