Beschreibung
Zusammenfassung:	An additive composition comprises at least one polyoxyalkylene compound and at least one ethylene polymer, wherein the at least one ethylene polymer, in addition to units derived from ethylene, comprises units of the formula (I): (see figure I) and optionally, units of the formula (II): (see figure II) wherein each R1 group independently represents hydrogen or methyl; wherein each R2 group independently represents an alkyl group having 5 or more carbon atoms; where in each R3 group independently represents hydrogen or methyl; wherein each R4 group independently represents an alkyl group having between 1 and 4 carbon atoms; wherein the proportion of units of formula (I) in the ethylene polymer is between 16 and 30mol%; and wherein the total proportion of units of formula (I) and formula (II) in the ethylene polymer is between 19 and 30mol%. The composition is particularly suitable for improving the lo w temperature properties of fuels having sharp distillation tails and low final boiling points.
