Abstract (en)
[origin: EP1526167A2] New additive comprises 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 23-27. An independent claim is also included for a fuel oil composition comprising a fuel oil of animal or vegetable origin and an additive as above.
