Beschreibung
Zusammenfassung:	The present invention relates to polyalkyl(meth)acrylates (PAMAs) containing dispersant repeating units and their use as an additive component to fuels, especially to middle distillates and blends thereof. The present invention further relates to a composition comprising polyalkyl(meth)acrylates containing dispersant repeating units as dispersing species and the use of said composition as an additive to fuels, especially to middle distillates and blends thereof, and for improving the cold flow properties of fuel oil and fuel oil compositions, especially to middle distillate fuels and blends thereof. La présente invention concerne des poly((meth)acrylates d'alkyle) (PAMA) contenant des unités récurrentes dispersives et leur utilisation comme constituant additif à des carburants, en particulier à des distillats moyens et leurs mélanges. La présente invention concerne en outre une composition comprenant des poly((meth)acrylates d'alkyle) contenant des unités récurrentes dispersives comme substance de dispersion et l'utilisation de ladite composition comme additif à des carburants, en particulier à des distillats moyens et leurs mélanges et pour améliorer les propriétés d'écoulement à froid de fioul et de compositions de fioul, en particulier les carburants de distillat et leurs mélanges.
