Abstract: The recent research progress in nonisocyanate polyurethane (NIPU) prepared by cyclocarbonate- and amino-oligomer and synthetic mechanism wherein were reviewed in this paper. The synthetic methods of cyclocarbonate oligomer and amino-oligomer were studied. The application area and prospect of NIPU were introduced, including research and industry development abroad. Combined with work practice, easily prepared, non-toxic, and cheap precursors were considered the important research field in the future.

Key words: nonisocyanate polyurethane, cyclocarbonate, amino-oligomer, research progress, application
