CO2共聚物的研究开发对环境保护、资源再利用及新材料研究领域都都具有重要的意义。与CO2共聚的单体是影响其共聚物结构、性能及成本的重要因素。综述了与CO2催化共聚单体的研究进展,这些单体主要包括二元共聚的环氧丙烷、环氧环己烷,三元共聚的某些单体。进一步就今后CO2催化共聚的发展方向进行了探讨,可望为CO2共聚物产业化发展提供参考。 The research and development of CO2 copolymer is of great significance in the field of environmental protection, resource reuse and new material research. Monomers copolymerized with CO2 are important factors affecting the structure, performance and cost of the copolymer. The progress of the research on CO2 comonomers is reviewed. These monomers mainly include binary copolymerization of propylene oxide, cyclohexene oxide and certain monomers of terpolymerization. In the future, the development of CO2 copolymerization is discussed, which is expected to provide a reference for the industrialization of CO2 copolymer.
