Abstract

Gegenstand der Erfindung ist ein Verfahren zur Verbesserung der Kaltfließeigenschaften von Ölen mit einem Schwefelgehalt von weniger als 500 ppm und einem Gehalt an n-Paraffinen der Kettenlänge C18 und länger von mindestens 8 Gew.-%, gekennzeichnet durch die Zugabe eines Additivs, enthaltend eine Mischung aus
  • A) 15 bis 50 Gew.-% eines Copolymers, enthaltend neben 87 bis 92 mol-% von Struktureinheiten, die sich von Ethylen ableiten;
  • a) 6,5 bis 12 mol-% Struktureinheiten, die sich von Vinylacetat ableiten,
  • b) 0,5 bis 6 mol-% Struktureinheiten, die sich von 4-Methylpenten-1 ableiten,
    mit der Maßgabe, daß die Summe der molaren Anteile der Struktureinheiten a) und b) 8 bis 14 mol-% beträgt,
    • und
  • B) 85 bis 50 Gew.-% mindestens eines weiteren Copolymers oder Terpolymers aus Ethylen und Vinylestern oder Acrylsäureestern, das für sich allein ein Kaltfließverbesserer ist.
    • Weitere Gegenstände der Erfindung sind ein Additiv zur Verbesserung der Kaltfließeigenschaften von Mineralölen und Mineralöldestillaten sowie Brennstoffölzusammensetzungen, die diese Additive umfassen.
