摘　　要：二氧化碳综合利用对于减轻温室效应和开发有机化工新碳源都具有重要价值。本文简要介绍了二氧化碳化学转化的研究意义,总结了其参与化学反应的主要途径,对比了二氧化碳基聚碳酸酯与双酚A型聚碳酸酯,指出开发催化二氧化碳与环氧化合物共聚反应的高效催化剂是该领域研究的重点。重点综述了二氧化碳与环氧化合物共聚各类催化剂的研究进展,并探讨了其优缺点。分析得出该研究领域进一步发展面临的主要问题是催化剂效率和共聚产物的性能与应用。产品由于具有生物降解性且其原料为储量丰富的二氧化碳,因而具有广阔的应用前景。Chemical fixation of CO2 is a very attractive subject not only from carbon resource utilization, but also from increasing environmental concerns. In this paper, the significance and methods of CO2 participation in chemical reactions are introduced. Carbon dioxide-based polycarbonates is compared with bisphenol-A polycarbonates, and the emphasis is highly efficient catalyst in copolymerization of CO2 and epoxides to produce aliphatic polycarbonates. Recent progress of the catalysts for copolymerization of CO2 and epoxides is reviewed, and their advantages and disadvantages are discussed. The difficulties in future research are pointed out. The copolymerization product has wide application prospect due to its biodegradability and carbon oxide as raw material.
