Abstract: The invention relates to copolymers comprising C14 to C50 olefins and at least two different olefin dicarboxylic acid esters and optionally maleic acid or maleic acid derivatives. The olefin dicarboxylic acid esters are, first, esters having linear C18 to C50 alkyl groups and, second, esters having short-chain linear, branched, or cyclic alkyl groups or esters having aromatic groups. The invention further relates to a method for producing such copolymers and to the use thereof as pour point depressants for crude oil, mineral oil, and/or mineral oil products, preferably as pour point depressants for crude oil.

Abstract: The invention relates to a method for reacting epoxides with a starter-compound in the presence of a double metallocyanide-compound as a catalyst with reduced induction times. The activation of the double metallocyanide-compound occurs by adding the epoxides to a mixture made from double metallocyanide-compounds and starter compounds at an inner pressure of the reactor of less than 1 bar. The invention also relates to a polyether which can be obtained by means of said method.

Abstract: The invention relates to polymers that can be obtained from 1-butene oxide and 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. The invention additionally relates to carrier oil formulations such as fuels containing an inventive polyether.
