Abstract: The invention relates to the use of substituted monoureas, diureas, polyureas, monourethanes, bisurethanes, or polyurethanes of the formula R1X-CO-NR3R4, in which X represents R2N or O, and R1 to R4 represent hydrogen, alkyl groups, alkenyl groups, cycloalkyl groups, aryl groups, or aryl-alkyl groups independently of one another, wherein at least one variable must contain four carbon atoms and the urea or urethane functionality can be present multiple times via bridge elements, in order to further improve the cold flow properties of mineral oils and crude oils which already contain an additional organic compound that is suitable for dispersing or aiding the dispersion of paraffin crystals precipitated at low temperatures and an additional organic compound that improves the cold flow behavior of mineral oils and crude oils.

Abstract: A copolymer obtainable by free-radical polymerization of (i) monomer units of the structure (M1) in which the variables are each hydrogen, alkyl groups, carboxyl groups or carboxyl derivative moieties, and (ii) monomer units of the structure (M2) in which R5 is the radical of a carboxylic ester of the formula -A-CO-O-R10 where A is an alkylene group and R10 is a hydrocarbyl radical, and in which R6, R7 and R8 are each hydrogen or alkyl radicals, and subsequent polymer-analogous reaction of the product formed with a long-chain hydrocarbyl alcohol. This copolymer is suitable for improving the cold flow properties of middle distillate fuels, especially those which consist of or comprise biofuel oils.
