Abstract:
1. A fuel oil composition F) comprising F1) a fuel oil of mineral origin and F2) a fuel oil of vegetable or animal origin, and a cold additive comprising the constituents A) at least one copolymer composed of ethylene and 8-21 mol % of a comonomer of at least one acrylic or vinyl ester having a C B) at least one comb polymer containing structural units composed of where the sum Q of molar averages of the carbon chain length distributions in the alkyl radical of monomer 1 on the one hand and the alkyl radical of the amide or imide moiety of monomer 2 on the other is from 21.0 to 28.0, where w w n n i is a serial variable for the individual chain lengths in the alkyl radical of monomer 1, and j is a serial variable for the individual chain lengths in the alkyl radical of the amide and/or imide moiety of monomer 2.
