    摘要： The present invention provides a process for efficiently obtaining polyethers having its high degree of polymerization by easily polymerizing substituted epoxides which could hardly or could not be made so far to provide a high degree of polymerization. That is, a polyether is obtained by a process which comprises ring-opening-polymerizing at least one substituted epoxide, except for propylene oxide and epihalohydrin, in the presence of a rare earth metal compound represented by the formula (I) and a reducing compound: Wherein M represents a rare earth element selected from Sc, Y and lanthanide, and L1, L2 and L3 are same as or different from each other and each of them represents an oxygen-binding ligand.

    摘要翻译： 本发明提供了一种通过容易聚合取代的环氧化物而有效获得聚合度高的方法，所述取代环氧化物几乎不能或不能达到提供高度聚合的程度。 也就是说，通过在式（I）表示的稀土金属化合物和还原性化合物的存在下，通过包括使环氧丙烷和表卤代醇除外的至少一种取代的环氧化物开环聚合的方法获得聚醚 ：其中M表示选自Sc，Y和镧系元素的稀土元素，L1，L2和L3彼此相同或不同，它们各自表示氧结合配体。
