Abstract: The invention relates to polymers that can be obtained from 1-butene oxide a nd from an alcohol while using a double metal cyanide compound as a catalyst, whereby the polyether has a quantity of unsaturated constituents equal to 6 or more mol %. The invention also relates to a method for producing a polyether of this type, and to the use of the inventive polyether as a carrier oil or in a carrier oil formulation, particularly in additive packets for gasolines. T he invention additionally relates to carrier oil formulations such as fuels containing an inventive polyether.

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.
