Abstract: Terpolymer made of (A) ethylene, (B) (i) C2- to C14-alkenyl esters of one or more aliphatic C1- to C20-monocarboxylic acids or (ii) C1- to C24-alkyl esters of acrylic acid or methacrylic acid and (C) olefinically unsaturated hydrocarbons selected from (iii) 5- to 7-membered cycloalkenes and (iv) a-olefins having from 6 to 20 carbon atoms. The said terpolymer is suitable as low-temperature flow improver in middle-distillate fuels. It lowers the minimum temperature at which low-temperature flow improver additives can be mixed into middle-distillate fuels, and improves the filterability of middle-distillate fuels comprising low-temperature flow improver additives.

Abstract: The invention relates to the use of a mixture comprising (A) 5 to 95 wt % of at least one oil-soluble polar nitrogen compound that can interact with paraffin crystals in middle distillate fuels in the cold, and (B) 5 to 95 wt % of at least one oil-soluble aliphatic compound having alkyl or alkenyl chain having at least 8 carbon atoms that can be obtained from aliphatic mono or dicarboxylic acids having 4 to 300 carbon atoms or derivatives thereof having mono or polyamines or having alcohols for reducing the cloud point in middle distillate fuels that have a CP value of -8.0°C or lower before the addition of additives by at least 1.5°C compared to the middle distillate fuel without additives at a dosing of the mixture from 50 to 300 wt ppm, with simultaneous non-deterioration of the response characteristic for reducing the cold filter plugging point upon addition of cold flow improvers.
