Abstract (en)

[origin: EP0344644A2] Paraffin-containing mineral oils from the group comprising crude oils, vacuum gas oils and residual oils which have improved flow properties, it being common to the mineral oils that paraffin crystallisation starts at a temperature below or equal to 30 degrees C and that they contain 1-10,000 ppm of at least one polymer P, from the class of polyalkyl(meth)acrylates or of polydialkylfumarates whose crystallization starts below 15 degrees C.
