摘要/Abstract

二氧化碳（CO₂）是一种丰富、廉价、无毒以及可再生的一碳资源，也是一种可用于聚合的绿色单体.基于CO₂的聚合是近年来的研究热点之一.目前广泛报道的是CO₂和环氧单体的聚合反应，经过几十年的发展已经成功实现工业化生产.最近几年，一些CO₂参与的新型聚合反应被陆续报道，这些工作大都通过两种途径实现从CO₂到高分子材料的转变.第一个途径是先将CO₂转化为可以聚合的单体，例如：内酯、环状碳酸酯和2，5-二呋喃甲酸等，再利用开环或者逐步聚合将单体转化为聚合物；另一个途径是直接以CO₂为单体和其他类型单体共聚得到聚合物.这两种途径对于发展CO₂参与的新型聚合反应，拓展CO₂基聚合物种类都具有重要意义.本综述按照CO₂直接还是间接参与聚合反应分类总结了近年来在CO₂制备高分子材料方面的进展，并对未来发展方向进行了简单阐述.

Carbon dioxide (CO₂) is an abundant, inexpensive, non-toxic and renewable C1 resource, and it is also a kind of green monomer. The polymerizations based on CO₂ have been one of the hot research topics. The copolymerization of CO₂ and epoxide monomers was widely studied in the past few years and has been industrialized. Some new polymerizations based on CO₂ have also been reported recently. There are two ways to produce polymeric materials from CO₂. One is converting CO₂ into monomers for further ring opening or step growth polymerizations, such as lactone, cyclic carbonates, furan-2,5-dicarboxylic acid. Another is directly using CO₂ as a monomer for the copolymerization with other monomers to generate polymers. They are both significant for developing new polymerizations based on CO₂ and expanding CO₂-based polymeric materials. The advances in converting CO₂ into polymeric materials during the past few years are summarized in this review and the perspective in this area is discussed.
Key words: carbon dioxide, alkyne monomer, cyclic carbonate, lactone, furan-2,5-dicarboxylic acid
