二氧化碳共聚反应新动向

New Progress in the Copolymerization of Carbon dioxide

概述了2000年以来二氧化碳共聚反应方面的新动向。传统催化体系研究趋于成熟,催化效率大幅提高,已开始进行工业化;新型高效催化剂及其助催化剂不断涌现;聚合工艺趋向于低压、短时、非溶剂、反应条件更温和;与二氧化碳共聚的单体种类更多。

The latest prcgress in the copolymerization of carbon dioxide and other monomers is summarized, Novel and effective catalysts, for example zinc β-diiminate complexes and （Salen） Cr｜｜｜Nu, have been reported. Carbon dioxide resins have been produced in a industrial scale using traditional rare earth or PBM catalysts. A very low even no pressure, a shorter time, and new techniques without organic solvents have been adopted in the copolymerization. Some new carbon dioxide polymers have been synthesized.
