CO2-Sourced Polymers: Synthesis, Property, Application

The polymeric materials could be synthesized directly from CO2 as a monomer, which are named as CO2-sourced polymers, mainly including polyurethane, polyurea, polycarbonate, and polyester. The CO2-sourced polymers are of some advantages compared to their conventional counterparts, such as environmental benignity without using toxic reagents, carbon reduction, degradability, and reproducibility. This chapter will review the advancements achieved in the CO2-sourced polymer synthesized directly and indirectly by using CO2 as a monomer over the past five years (from 2019 to present). Herein, we pay main attention to the synthetic methodologies, the structure, properties, and possible applications of several kinds of important CO2-sourced polymers such as polyurethanes, polyureas, polycarbonates, and polyesters.
