Recent progress in the synthesis of polymers based on carbon dioxide

The alternating copolymerization of carbon dioxide and epoxide to give polycarbonate has attracted the attention of many chemists, because it is one of the most promising methodologies for the utilization of carbon dioxide as a safe, clean, and abundant raw material in the synthetic chemistry. Recent developments of the catalysts for the alternating copolymerization are based on the rational design of metal complexes, especially complexes of transition metal with well-defined structures.
