摘要：
The invention relates to a block copolymer and the use thereof as a cold resistance additive of a fuel or combustible. The block copolymer comprises: (i) a block A consisting of a chain of structural motifs derived from at least one α,β-unsaturated alkyl methacrylate or acrylate monomer; and (ii) a block B consisting of a chain of structural motifs derived from at least one α,β-unsaturated monomer containing at least one aromatic ring. The invention also relates to an additive concentrate containing such a copolymer and to the use thereof as a TLF booster and, advantageously, as an anti-sedimentation additive.
