Abstract (en)
[origin: EP1526168A2] 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) comprising (meth)acrylate, vinyl ester, vinyl ether, (meth)acrylamide, allyl ether or diketene units with C8-C16 alkyl groups, where the sum of the molar average alkyl chain lengths in (II) is 11-14. 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.
