Abstract
La présente invention a pour objet l’utilisation, comme additif dans une composition de carburant ou de combustible, d’un ou plusieurs polymères comprenant au moins 70% en moles de motifs de formule (I): (I)dans laquelle R1 représente un atome d’hydrogène ou un groupement méthyle ; E représente -O-CO-, ou -CO-O- ou -NH-CO- ou -CO-NH- ; et G représente un groupe de formule -R2-Q dans laquelle R2 désigne une chaine hydrocarbonée en C1 à C3 4 et Q désigne un groupement comprenant une fonction ammonium quaternaire et éventuellement un ou plusieurs groupements hydroxyle. La présente invention concerne également des compositions de carburants et de combustibles additivées avec de tels polymères, ainsi que des compositions d’additifs (ou « packages d’additifs ») contenant ces polymères, en combinaison avec au moins un additif fluidifiant à froid (CFI).
