Abstract (en)
[origin: EP1541662A1] Fuel oil composition comprises a mineral oil, an oil of vegetable or animal origin, and a cold flow improver comprising a copolymer (I) of ethylene and an acrylic or vinyl ester and a comb polymer (II) of an olefin (IIa) with an alkyl group attached to the double bond and an ethylenically unsaturated dicarboxylic acid N-alkyl amide or imide (IIb), where the sum Q of the molar average alkyl chain lengths in (IIa) and (IIb) is 21-28. Fuel oil composition comprises a mineral oil, an oil of vegetable or animal origin, and a cold flow improver comprising a copolymer (I) of ethylene and 8-21 mole% of an acrylic or vinyl ester with a C1-C18 alkyl group and a comb polymer (II) of an olefin (IIa) with a C8-C18 alkyl group attached to the double bond and an ethylenically unsaturated dicarboxylic acid amide or imide (IIb) with a C8-C16 alkyl group attached to the amide or imide group, where the sum Q of the molar average alkyl chain lengths in (IIa) and (IIb) is 21-28.
