Poly(propylene carbonate) (PPC) is a new completely biodegradable plastic based on carbon dioxide. Polymerization of PPC is not only one of the effective routes for utilization of carbon dioxide

but is expected to become a partial substitute for the traditional plastics. Focusing on the core issues which limit the large-scale application of PPC in this paper: poor mechanical and thermal properties

and starting from the three areas including chemical modification

blending modification and reinforcing modification

we have reviewed the recent progress in current situation and property modification of PPC

and have discussed the crucial problems in the PPC modification

and have also proposed the breakthrough of PPC with high performance

which could provide a theoretical guidance for the application of PPC. Finally

the outlook for the PPC modification and its future is summarized.
