摘要：The invention relates to a block copolymer and the use thereof as a coldresistance additive of a fuel or combustible. The block copolymer comprises: (i) a block Aconsisting of a chain of structural motifs derived from at least one α,β-unsaturated alkylmethacrylate or acrylate monomer; and (ii) a block B consisting of a chain of structuralmotifs derived from at least one α,β-unsaturated monomer selected from styrenederivatives, the aromatic ring of which is substituted by at least one group R selectedfrom the groups: C1 to C24 alkyl esters, and preferably acyclic linear or branched C1 toC12 hydrocarbonated chains, said chain being substituted by at least one groupcontaining a quaternary ammonium salt. The invention also relates to an additive

concentrate containing such a copolymer and to the use thereof as an anti-sedimentationadditive, and advantageously, as a TLF booster additive.
