Abstract
Novel furanic polyureas were synthesised by solution polycondensation reactions between difuranic diamines and aliphatic diisocyanates and then converted to the corresponding poly(parabanic acid)s by heterocyclisation with oxalyl chloride. These condensation reactions and chemical modifications were first studied with model compounds. The polymers were characterised by FTIR and 1H-NMR spectroscopy and inherent viscosity.
