用钴配合物研究了环氧丙烷与一氧化碳的交替共聚合。纳科（CO）4/胺催化剂体系选择性地产生带有可聚合的巴豆酸酯端基的低聚（3-羟基丁酸酯），而使用Co2（CO）8作为钴源导致巴豆酸酯端基的浓度较小和聚合度高。纳科（CO）4/胺体系对巴豆酸酯的高选择性是由于其反应条件更碱性。© 2004 Wiley Periodicals，Inc.聚合物科学杂志A部分：聚合物化学42：4666-4670，2004年
The alternating copolymerization of propylene oxide and carbon monoxide was investigated with cobalt complexes. The NaCo(CO)4/amine catalyst system selectively yielded oligo(3-hydroxybutyrate)s bearing a polymerizable crotonate end group, whereas the use of Co2(CO)8 as a cobalt source resulted in a smaller concentration of the crotonate end group and a high degree of polymerization. The high selectivity for the oligoesters with the crotonate end group with the NaCo(CO)4/amine system was attributed to its more basic reaction condition. © 2004 Wiley Periodicals, Inc.
