OND AUSGABE DER
AÜSLEGESCHRIFT.· 24. DEZEMBER 1959
Gegenstand des Patentes 1 037 630 ist die Verwendung von 0,01 bis 20 Gewichtsprozent eines öllöslichen Mischpolymeren eines Alkoxymischesters, der von einer mit einem aliphatischen Alkohol teilweise veresterten, mit einem Alkylenoxyd umgesetzten ungesättigten Dicarbonsäure abstammt, mit einem ungesättigten Ester als Schmierölzusatz.
Die Zusatzstoffe gemäß Hauptpatent sind gute Detergentien, verursachen keine störenden Abscheidungen in Verbrennungsmotoren und haben einen erhöhten Viskositätsindex und einen gesenkten Fließpunkt.
Als Zusatzstoffe gemäß vorliegender Erfindung werden 0,01 bis 20 Gewichtsprozent eines öllöslichen Mischpolymeren aus einem ungesättigten Ester und einem solchen Alkoxymischester verwendet, dessen zur Teilveresterung der ungesättigten Dicarbonsäure eingesetzte alkoholische Komponente ein cyclischer oder aromatischer Alkohol oder ein Phenol ist.
Als aromatische Alkohole sind Phenylmethanol oder Phenyläthanol, ferner sek. aromatische Alkohole wie Diphenylmethanol oder Diphenyläthanol, weiterhin tert. aromatische Alkohole wie Triphenylmethanol oder Triphenyläthanol zu nennen.
Cyclische Alkohole sind z. B. Cyclobutanol und Cyclohexandiol. Geeignete Phenole sind unter anderem Monophenole, Polyphenole, Naphthole und Anthranole oder substituierte Phenole, namentlich Monophenole, die durch eine C8 bis C24-Alkylkette substituiert sind. Bevorzugt wird z. B. Dodecylphenol, der etwa durch Substitution eines Phenols mit einer durch Propylenpolymerisation erhaltenen Alkylkette gewonnen werden kann.
Die bevorzugten Dicarbonsäuren und Alkylenoxyde entsprechen denen des Patents 1 037 630; zu nennen sind hier ebenfalls vornehmlich Fumarsäure, Maleinsäure als Dicarbonsäuren und Äthylenoxyd oder Propylenoxyd als Alkylenoxyde.
Die Zusatzstoffe sind Mischpolymere der Alkoxymischester mit ungesättigten Estern z. B. Vinylacetat, ferner Estern eines oder mehrerer C8- bis C12-Alkohole wie Octylalkohol und einer a-/?-ungesättigten Monocarbonsäure, insbesondere die Acrylate und Methacrylate.
Beispiel
1 Mol Maleinsäureanhydrid wird mit 1 Mol Dodecylphenol in Gegenwart von 1 % p-Toluolsulfonsäure als Katalysator teilverestert; das Reaktionswasser wird mit Xylol entfernt.
Dieser Monoester wird mit Äthylenoxyd bei 140° C in Gegenwart von Spuren eines BF3-Äther-Komplexes in 8 Stunden kondensiert. Der äthoxylierte Monoester Schmierölzusatz

wird dann mit 25 Gewichtsprozent Vinylacetat in Gegenwart von Benzoylperoxyd als Katalysator 6 Stunden bei 70° C mischpolymerisiert.
Der Alkoxymischester wird in einem paraffinbasischen Mineralöl einer Viskosität von 35 cst bei 37,8° C und mit einem Viskositätsindex von 112 in verschiedenen Mengen gelöst: Die eine Lösung — Lösung A — enthält 1 Gewichtsprozent, die andere Lösung — Lösung B — 5 Gewichtsprozent Zusatzstoff.
Die Detergenswirkung dieser Lösungen wird in der Weise untersucht, daß 10 g Trockenschlamm eines gebrauchten Motoröls in 90 g des Testöls bei 93,3° C suspendiert werden und die Suspension 24 Stunden bei dieser Temperatur stehengelassen wird. Danach werden die oberen 25 ecm des Gemisches in ein Zentrifugenrohr abgegossen und mit Hexan auf 100 ecm aufgefüllt. Dieses Gemisch wird dann zentrifugiert und der Schlamm gesammelt, um die Fähigkeit der ölvermischung zur Schlammsuspendierung auszuwerten. Die Wirksamkeit des Zusatzstoffes wird durch das Verhältnis des Volumens des suspendierten
