Aschefreie, stickstoffhaltige Verbindungen, wie Mischpolymerisate aus polymerisierbaren Aminen oder Amiden mit langkettigen Acrylsäureestern, sind als vorzügliche Reinigungsmittel bekannt. Unter den Arbeitsbedingungen von Motoren ist die Wirksamkeit hinsichtlich der Korrosions- und Abnutzungsfestigkeit %doch gering.
Es wurde nun gefunden, daß diese Eigenschaften wesentlich verbessert werden können, wenn ein Mineralschmieröl, enthaltend entweder ein Misch- JO polymerisat aus einem heterocyclischen, stickstoffhaltigen Monomeren und einem stickstofffreien Monomeren oder ein Kondensationsprodukt aus einer Alkylbernsteinsäure mit höhermolekularem Alkylrest und einem Polyamin, zusätzlich das öllös- t5 liehe Umsetzungsprodukt eines Arylphosphats der Formel

Das erfindungsgemäße Mineralschmieröl ist nicht korrodierend, nicht schlammbildend, verschleißhindernd und stabil. Die bevorzugten Mischpolymerisate sind Mischpolymerisate von Stearylmethacrylat, Laurylmethacrylat, gegebenenfalls Ci- bis d-Alkyhnethacrylaten und 2-Methyl-5-vinylpyridin oder S-ÄthyW-vinylpyridin. Ebenfalls geeignet sind Polymerisate aus Vinylpyrrolidon und einem oder mehreren Estern einer Acrylsäure mit einem aliphatischen Alkohol, wie sie in der belgischen Patentschrift 550 442 und der britischen Patentschrift 808 665 beschrieben sind.

Die Kondensationsprodukte aus einer Alkylbernsteinsäure umfassen polyalkenyl-monosubstituierte Bernsteinsäureimide, wie N-Dialkylaminoalkylpolyalkenylbernsteinsäureimide, z. B. N-Dimethylaminopropylpolybutenylbernsteinsäureimid, oder die PoIyalkylenpolyaminderivate von Bernsteinsäureanhydrid, wie das Tetraäthylenpentaminderivat von Polybutenylbernsteinsäureanhydrid.
Die bekannten Versuche zur Herstellung eines Mischpolymerisats sind nachstehend beschrieben:
A. 30 Teile Stearylmethacrylat, 51 Teile Laurylmethacrylat, 14 Teile Methylmethacrylat und 5,0 Teile 2-Methyl-5-vinylpyridin werden in einen 11401 fassenden Autoklav aus korrosionsbeständigem Stahl gegeben. Dann wird ein Gemisch (50 : 50) von Benzol und neutralem Erdöl dem Autoklav zugesetzt, so daß sich 1 Teil des Lösungsmittelgemisches auf 3 Teile des Monomerengemiscb.es ergibt. Dann werden 0,25 Ditert-butylperoxyd zugesetzt und das Gemisch etwa 7 Stunden auf 1200C erhitzt.
Nach Beendigung der Reaktion wird das Benzol durch Spülen mit Stickstoff bis zu einer Endtemperatur von 120°C/10 Torr abgestreift. Der benzolfreie Rückstand wird dann mit neutralem öl auf einen Polymerengehalt von etwa 30 Gewichtsprozent verdünnt und bei 100 bis 1200C filtriert. Das Mischpolymerisat hat ein Molekulargewicht von etwa 600000 und einen Stickstoffgehalt von 0,54%.
