    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: It is an object of the present invention to provide a load leveling system of a power system capable of attaining load leveling in a distribution substation unit and a method thereof. Disclosed is a load leveling system of a power system with a controller having a major customer and lower transforming apparatus, and with a customer connected to the lower transforming apparatus via a low-voltage line. The system also has a communication unit between the customer and its own system, and control use time zones of devices within the customer; an electric demand prediction unit, and a first load leveling processing unit. By employing such an arranged system, it becomes possible to provide a load leveling system of a power system capable of realizing load leveling of both a distribution substation unit and a pole transformer unit.
