Title
(EN) USE OF SPECIFIC COPOLYMERS FOR LOWERING THE COLD FILTER PLUGGING POINT OF FUELS
(FR) UTILISATION DE COPOLYMÈRES SPÉCIFIQUES POUR ABAISSER LA TEMPÉRATURE LIMITE DE FILTRABILITÉ DE CARBURANTS OU COMBUSTIBLES
Abstract
(EN)
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 R1, R2 and R3, which are the same or different, are a hydrogen atom or a C1 to C4 alkyl group, and R4 is a C5 to C17 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.
(FR)
La présente invention a pour objet l'utilisation, pour diminuer la température limite de filtrabilité d'une composition de carburant ou de combustible, d'un ou plusieurs copolymère(s) formé(s) des motifs suivants : - de 80 à 95% en moles d'un motif de formule (I): - et de 5 à 20% en moles de motif(s) de formule (II): dans laquelle R1, R2, et R3, identiques ou différents, représentent un atome d'hydrogène ou un groupe alkyle en C1 à C4, et R4 représente un groupe alkyle linéaire en C5 à C17, ledit copolymère ayant une masse molaire moyenne en nombre Mn comprise entre 3000 et 7000 g.mol-1. L'invention concerne également des compositions d'additifs contenant un tel copolymère, ainsi que des compositions de carburant et de combustible additivées avec de tels copolymères.
