摘要

An additive for fuel oils containing at least one copolymer of ethylene and unsaturated esters, at least one oil-soluble polar nitrogen compound, which is a product of the reaction of amines of the formula nr⁶R⁷R⁸, wherein r⁶, R⁷ and r⁸ can be identical or different, and at least one of these groups for c₈-C.₃₆-Alkyl, c.sub.2₆-C.₃₆-Cycloalkyl, c₈-C.₃₆-Alkenyl, in particular c₁₂-C.₂₄-Alkyl, c.sub.2₁₂-C.₂₄-Alkenyl or cyclohexyl, and the remaining groups either hydrogen, c₁-C.₃₆-Alkyl, c.sub.2₂-C.₃₆-Alkenyl, cyclohexyl, or a group of the formulae (a - o -)_x-E or - (ch₂)_n-nyz, wherein a for an ethyl - or propyl group, x is a number from 1 to 50, e = h, c₁-C.₃₀-Alkyl, c.sub.2₅-C.₁₂-Cycloalkyl or c₆-C.₃₀-Aryl, and n = 2, 3 or 4, and y and z independently of one another are h, c₁-C.₃₀-Alkyl or – (a - o)_x , with compounds containing at least contain an acyl group, and at least one aromatic compound of formula 1, where r is h or c₁- to c₄-Alkyl,or 4 - hydroxy - 3 methoxyphenyl - propionic acid.
