| abstract |
The present invention relates to the use, in order to lower the cold filter plugging point of a fuel composition, of one or more copolymer(s) consisting of the following units: - 80 to 95 mol% of a unit of formula (I): - and 5 to 20 mol% of unit(s) of formula (II): wherein R 1 , R 2 and R 3 , which are the same or different, are a hydrogen atom or a C 1 to C 4 alkyl group, and R 4 is a C 5 to C 17 linear alkyl group, said copolymer having a number average molecular weight Mn of 3000 to 7000 g.mol -1 . The invention also relates to additive compositions containing such a copolymer, as well as to fuel compositions containing such copolymers as additives. |
