The invention relates to a block copolymer and its use as a cold resistance additive of a fuel or fuel. The block copolymer comprises; (i) a block A consisting of a chain of structural portions derived from one or more a, β-unsaturated, acrylate or alkyl methacrylate monomers, (ii) a block B consisting of a chain of structural portions derived from one or more a, β-unsaturated monomers containing at least one aromatic core. The invention also relates to an additive concentrate containing such a copolymer, as well as its use as a TLF enhancer and, advantageously, as an anti-sedimentation additive. |
