Notes:
Carbodiimides are formed with simultaneous evolution of CO2 by the reaction of basic catalyst with sterically hindered isocynates. Another generally applicable synthesis of carbodiimides involves intermediate formation of cyclic adducts of isocyanates and carbodiimides, which, upon cleavage, exchange the isocyanate and carbodiimide functions. Both processes are suitable for the preparation of polycarboiimides. Several commercial applications of mono- and polycarbodiimides are pointed out.
