Abstract: The invention relates to the use of substituted diureas, polyureas, 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 represent a group with at least four carbon atoms and the urea or urethane functionality must be present multiple times via bridge elements, in order to improve the use properties of mineral and synthetic nonaqueous industrial liquids.

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.
