二氧化碳和环氧化物共聚可生成聚烷撑碳酸酯,而为实现利用二氧化碳的此一极好途径,还需从理论和实践上探明高度活化二氧化碳的方法。本文介绍了本领域的研究现状,包括反应的催化体系、反应机理、反应条件、聚烷撑碳酸酯的性质、改性方法和应用;还介绍了国内外科学家为催化剂效率而作的努力。 The copolymerization of carbon dioxide and epoxides produces polyalkylene carbonate, and in order to achieve this excellent way to utilize carbon dioxide, there is a need to find both theoretically and practically a method of highly activated carbon dioxide. This paper introduces the research status in this field, including the catalytic system of the reaction, the reaction mechanism, the reaction conditions, the properties of the polyalkylene carbonate, the modification method and its application. The efforts of domestic and foreign scientists for the catalyst efficiency are also introduced.
