Advances in the Synthesis of CO2-Based Polycarbonate Catalyzed by Zinc Glutarate

Carbon dioxide (CO2) is a non-toxic, harmless, stable, abundant and renewable C1 resource. In past decades, CO2-based polyesters synthesized from CO2 have attracted much attention from both industry and academia. Among them, zinc dicarboxylate catalyzes the copolymerization of CO2 and epoxide to form poly(propylene carbonate), which has become an important way for CO2 utilization. In particular, zinc glutarate catalyzes the copolymerization of CO2 and epoxide, including the terpolymerization with the addition of acid anhydrides or cyclic esters, etc. In this paper, the progress of zinc dicarboxylate catalyzed CO2-based copolymerization are reviewed. The development, structure and activity of the catalyst and the product performance of the catalyst are systematically summarized. The advantages and disadvantages of zinc dicarboxylate catalyst in the polymerization process are analyzed and compared. Finally, the perspectives and challenges of catalysts are also discussed.
