Abstract: The present invention relates to a process for reacting epoxides with an initiator compound in the presence of a double metal cyanide compound as a catalyst, said process having a shortened induction period, and the double metal cyanide compound being activated by adding the epoxide to a mixture of double metal cyanide compound and initiator compound at an internal reactor pressure of less than 1 bar, and also to the polyethers themselves obtainable by such a process.

Abstract: The present invention relates to polyethers which are obtainable from 1 -butene oxide and an alcohol using a double metal cyanide compound as a catalyst and have a content of unsaturated components of 6 mol% or more, to a process for preparing such a polyether and also to the use of a polyether according to the invention as a carrier oil or in a carrier oil formulation, in particular in additive packages for gasoline fuels, and furthermore also to carrier oil formulations and also to fuels comprising a polyether according to the invention.

Abstract: A method for working up polyether-mono-ols (I) obtained by ring-opening polymerization of epoxides with hydroxy-functional starters in presence of heterogeneous catalysts involves separating the catalyst from the product (I) by a membrane separation process. An independent claim is also included for a method for the production of (I) by ring-opening polymerization of epoxides followed by a work-up process using a separation step as above.
