New parabanate products containing 1, 3, 5, 7-tetraazabicyclo[3, 3, 0]octane-2, 6-dione are described. The synthesis of αω-diisocyanato-telechelics starting from two diisocyanates having a preformed parabanic unit using a [3+2] dipolar cycloaddition reaction was studied. The obtained products were characterized by IR spectroscopy, elemental and thermogravimetric analyses and solubility tests. The proposed structure was confirmed by analytical data.
