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
