Es ist bekannt, daß polypolare Mischpolymerisate, die basische Aminostickstoffgruppen oder Kohlenwasserstoffgruppen
und/oder öllösliche Carbonsäuregruppen als Sutstituenten enthalten, zur Verbesserung
des Reinigungsvermögens, dis Viskositätsindex und
des Stockpunktes von Schmierölen geeignet sind. Solchen Schmierölen müssen aber zur Verbesserung
ihrer Eigenschaften zusätzlich noch Phosphor- und/oder
Schwefelverbindungen zugemischt werden.
Auch sind Schmiermittel bekannt, welche als Dispergiermittel und zur Verschleißminderung Mischpolymerisate
enthalten, welche durch Umsetzung einer polymerisierbaren, basischen, heterocyclischen Stickstoffverbindung,
wie Vinylpyridin, mit einer anderen polymerisierbaren Verbindung, die jedoch keine
Gruppen mit heterocyclischen! Stickstoff enthalten, wie Acrylsäureester, erhalten werden. Zur Verbesserung
ihrer verschleißverhindernden Wirkung benötigen diese Schmiermittel ebenfalls noch weitere Zusätze,

Es wurde nun gefunden, daß Schmiermittel einer verbesserten Reinigungswirkung und einer verminderten
Neigung zur Schlammbildung erhalten werden können, wenn man einem Mineralschmieröl 0,1 bis
10 Gewichtsprozent eines oder mehrerer Mischpolymerisate zusetzt, die an der Hauptkohlenwasserstoffkette
