Based on the viewpoint of environmental protection,relative development of the fixation and usage of carbon dioxide as cheap Cl raw material has been drawing much attention in industrial chemistry and bio-technology.Since the pioneering work of Inoue in 1969 that carbon dioxide copolymerized with alkene oxides to yield aliphatic polycarbonates,chemical fixation of CO2 has been greatly developed in the past four decades,while copolymerization of CO2 and cyclic imines to give poly(urethane-amine)s was just of little attention for kinds of reasons.
