摘要 本文研究了二茂基烯丙基稀土化合物Cp2 LnC3 H5(Ln =Sm ,Yb)对ε 己内酯的催化聚合反应。稀土化合物的催化聚合活性随温度提高而提高 ,钐化合物的催化活性要高于镱化合物。 Caprolactone was polymerized by complexes of Cp 2LnC 3H 5 (Ln=Sm, Yb). The catalytic activity increased with temperature increasing and the samarium complex displayed higher catalytic activity than the ytterbium complex. A polymerization mechanism was proposed.
