Abstract

Paraffinhaltige Mineralöle aus der Gruppe der Rohöle, Vakuumgasöle und Rückstandsöle, die verbesserte Fließeigenschaften besitzen, wobei den Mineralölen gemeinsam ist, daß der Beginn der Paraffinkristallisation bei einer Temperatur kleiner/gleich 30 Grad C liegt und daß sie einen Gehalt von 1 - 10 000 ppm mindestens eines Polymeren P, ausgewählt aus der Klasse der Polyalkyl(meth)acrylate oder der Polydialkylfumarate besitzen, deren Kristallisationsbeginn unterhalb 15 Grad C liegt. Mineral oils from the group of crude oils containing paraffin, Vacuum gas oils and residual oils, the improved Have flow properties, being the mineral oils common is that the beginning of paraffin crystallization at a temperature less than or equal to 30 degrees C and that they have a content of 1 - 10,000 ppm at least one Polymers P selected from the class of Polyalkyl (meth) acrylates or the polydialkyl fumarates have a crystallization start below 15 degrees C. lies.
