Abstract
2-Furfuryl isocyanate and 2-furyl isocyanate were polymerized with several anionic initiators. Cyclic trimers and linear polymers were obtained. These products were characterized by elementary analysis, IR and 1H-NMR spectroscopy, DSC, TGA, polarized-light microscopy, vapour-pressure osmometry and vacuum pyrolysis. The polymers possess a high degree of crystallinity. Their thermal decomposition yields the monomer and the cyclic trimer.
