摘要

Use of specific copolymers for lowering the limit temperature of filterability of fuels or combustibles The present invention relates to the use, to reduce the limit temperature of filterability of a fuel or fuel composition, of one or more copolymer (s ) formed from the following units: - from 80 to 95% by moles of a unit of formula (I): (I), and - from 5 to 20% by moles of unit (s) of formula (II) : (II) in which R1, R2, and R3, identical or different, represent a hydrogen atom or a C1 to C4 alkyl group, and R4 represents a saturated or unsaturated C5 to C17 hydrocarbon group. The invention also relates to additive compositions containing such a copolymer, as well as fuel and fuel compositions additives with such copolymers.
