二氧化碳与环氧环己烷共聚的研究进展

摘要

A review is provided of the current status, progress, and new trend of the research on various catalysts applicable to copolymerization of carbon dioxide and cyclohexene oxide. It is pointed out that, as a kind of cheap, abundant, and non-toxic starting materials, carbon dioxide can be adopted to copolymerize with cyclohexene oxide so as to synthesize aliphatic polycarbonate copolymers possessing good biodegradability. However, the copolymerization of carbon dioxide with cyclohexene oxide is nearly infeasible under common conditions, because carbon dioxide is highly chemically stable and has a high thermodynamic stability. Therefore, it is imperative to develop novel catalysts with high efficiency and selectivity for the copolymerization of carbon dioxide and cyclohexene oxide.%综述了国内外用于二氧化碳与环氧环己烷共聚的各类催化剂的研究现状、进展及研发新动向.指出二氧化碳作为一种廉价、无毒、可循环利用的理想原料,利用其和环氧环己烷共聚可合成具有良好生物降解性能的脂肪族聚碳酸酯.但二氧化碳具有较高的热力学稳定性,其和环氧环己烷共聚过程在一般情况下难以实现,故迫切需要开发高效、高选择性的催化剂.
