摘　　要：近年来,超临界二氧化碳(sc-CO2)在聚合反应中的应用受到了越来越多的关注。本文主要综述了以sc-CO2为反应介质的自由基聚合、阳离子聚合、过渡金属催化聚合、热致开环聚合、溶胶-凝胶聚合以及氧化耦合聚合的研究概况。一系列研究结果表明sc-CO2是非常有前途的反应溶剂,在高分子合成领域将会有更加广阔的应用前景。In recent years, more and more attention has been paid to supercritical carbon dioxide. This paper mainly reviewed the preparation of polymers that has been carried out in supereritical carbon dioxide. A number of polymerization reactions, such as free-radical polymerization, cationic polymerization, transition metal-catalyzed polymerization, thermal ring-opening polymerization, sol-gel polymerization and oxidative coupling polymerization are described in details. It indicates that supercritical carbon dioxide will have a great impact on the field of polymer synthesis in future.
