摘 要: 本文介绍以超临界CO2流体为介质的高分子合成的研究进展。说明可在超临界二氧化碳中实施氟代单体的自由基溶液聚合、甲基丙烯酸甲酯和苯乙烯的分散聚合、丙烯酸的沉淀聚合、丙烯酰胺的反相乳液聚合以及异丁基乙烯基醚的阳离子聚合等多种聚合反应。这显示出超临界CO2是一种对环境无污染且价廉的替代溶剂。 This review summarizes the polymer preparation that has been carried out in supercritical carbon dioxide.A number of polymerization reactions,such as the homogeneous free radical polymerization of flourinated monomers,the dispersion polymerization of methyl methacrylate and styrene,the precipitation polymerization of acrylic acid,the inverse emulsion polymerization of acrylamide and the cationic polymerization of isobutyl vinyl ether,can be conducted in supercritical carbon dioxide.This indicates that a wide range of polymers can be prepared in this environmentally sound and inexpensive supercritical carbon dioxide.
