Abstract

Beschrieben wird die Verwendung von Copolymeren aus Acryl- und/oder Methacrylsäureestern höherer Alkohole bzw. Alkohol­ schnitte mit wenigstens 16 C-Atomen im Alkoholrest und nicht mehr als 5 Gew.-%, bevorzugt 0,5 bis 2,5 Gew.-% Maleinsäure­ anhydrid als Fließverbesserer in paraffinreichen Rohölen und/­ oder Erdölfraktionen mit Eigenfließpunkten oberhalb 25 °C zur Absenkung deren Fließpunkte auf Werte unterhalb 15 °C, bevor­ zugt unter 10 °C. The use of copolymers of acrylic and / or methacrylic acid esters of higher alcohols or alcohol cuts with at least 16 carbon atoms in the alcohol residue and not more than 5% by weight, preferably 0.5 to 2.5% by weight, of maleic acid anhydride as a flow improver in paraffin-rich crude oils and / or petroleum fractions with their own pour points above 25 ° C Lowering their pour points to values below 15 ° C before moves below 10 ° C.
