A preliminary study of polyureas and poly(parabanic acid)s incorporating furan rings

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 H-1-NMR spectroscopy and inherent viscosity.
