Den Schmierölen werden bekanntlich Zusätze beigemischt. Diese oft metallhaltigen Zusätze haben
jedoch den Nachteil, daß sie Abscheidungen auf der Oberfläche des Kolbens und an den anderen Wänden
der Verbrennungskammer sowie an Ventilen und Zündkerzen verursachen.
Es wurde nun gefunden, daß man ein wertvolles Schmieröl, welches die aufgeführten Nachteile nicht
zeigt, erhält, wenn man einem Schmieröl 0,1 bis 10 Gewichtsprozent eines Polyglykols der Formel
Schmieröl
worin M ein Polysaccharid, ein Polypeptid, ein Polymerisations- oder Kondensationsprodukt, vorzugsweise
ein polymerer aliphatischer KW-Rest mit einem Molgewicht von 50 OQP bis 1 000 000 ist, Li und L2
zweiwertige Gruppen sind, R ein aliphatischer oder cycloaliphatischer KW-Rest mit 4 bis 30 C-Atomen
ist, P ein Polyglykolrest mit mindestens 5Alkylenoxydeinheiten und 2 bis 7 C-Atomen ist und χ und y
ganze Zahlen sind, wobei M gegebenenfalls durch eine oder mehrere Carboxyl-, Amidocarbonyl-, oxy-
und aminosubstituierte Alkylamid-, Alkylestergruppen oder heterocyclische Stickstoff- oder sauerstoffhaltige
Gruppen substituiert ist und welches dadurch gekennzeichnet ist, daß Li und L2 ein Alkylenrest
oder eine Oxy-, Carbonyl-, Sulfonyloxy-, Iminocarbonyl-, Iminocarbonyloxy-, Ureylen-, Sulfid-,
Phosphonyloxy- und Iminogruppe oder eine Kombination dieser Gruppen mit Alkylenresten mit
1 bis 7 C-Atomen ist, zusetzt.
Es sind bereits aus der französischen Patentschrift 1150 894 und der britischen Patentschrift 759 918
Polyglykolester der oben angegebenen Formel bekannt, denen gegenüber sich die beanspruchten Verbindungen
dadurch unterscheiden, daß Li und L2 zweiwertige Reste sind, die nicht veresterbar sind.
Die beanspruchten Verbindungen verbessern die Eigenschaften der Schmieröle noch mehr als die
Verbindungen nach obigen Patentschriften.
Die Polyglykolzusätze nach vorliegender Erfindung sind also vorwiegend aliphatische Kohlenwasserstoffmakromoleküle
mit nicht als Ester verketteten Polyglykolgruppen, die bis zu etwa 99,9 Gewichtsprozent
öllöslichmachende Kohlenwasserstoffgruppen enthalten, wie aliphatische und cycloaliphatische Kohlenwasserstoffgruppen
mit mindestens je 4 Kohlenstoffatomen, und haben mindestens etwa 0,1 Gewichtsprozent
Polyglykolgruppen mit mindestens 5 Alkylenoxydeinheiten in jeder Polyglykolgruppe.
Der Hauptbestandteil der erwähnten Polyglykolzusätze ist das vorwiegend aliphatische Kohlen-Anmelder:

Wasserstoffmakromolekül mit den Polyglykolgruppen. Der aliphatische Kohlenwasserstoffteil verleiht dem
Zusatz die öllöslichkeit, und der Polyglykolteil gibt ihm die Polarität. Die Vereinigung dieser Teile in dem
Makromolekül ergibt einen Zusatz, der gute Reinigungs- und Antiverschleißeigenschaften hat.
Beispiele für Li und L2 sind Alkylengruppen, wie
Methylen-, Oxy-, Carbonyl-, Sulfonyloxy-, Iminocarbonyl-, Ureylen-, Imino-carbonyloxy-, Sulfid-,
Phosphonyloxy- und Iminogruppen oder Kombinationen dieser Gruppen mit Alkylengruppen mit je
bis 7 Kohlenstoffatomen.
Der Rest M kann noch mit anderen Gruppen, z. B. der Carboxylgruppe, der Amidocarbonylgruppe,

worin R eine Alkylengruppe mit vorzugsweise nicht mehr als 7 Kohlenstoffatomen bedeutet, oxy- und
aminosubstituierten Alkylestergruppen, heterocyclischen stickstoffhaltigen Gruppen, wie Pyridyl-,
Pyrrolidyl- und Carbazolylgruppen, Epoxygruppen, z. B. die Glycidylgruppen und Cyangruppen, substituiert

Polyäthylenglykolgemische mit durchschnittlichen Molekulargewichten von 220, 400, 1000,
1540, 2000 oder 10 000 und deren Monoalkyläther,
Poly -1,2 - propylenglykolgemische mit durchschnittlichen
Molekulargewichten von 425, 1025 oder 10000 und deren Monoalkyläther.
Das beanspruchte Polyglykol kann in dem verwendeten Schmieröl zu mindestens 0,5%, vorzugsweise
zu 2 Gewichtsprozent oder mehr, löslich sein. Die Löslichkeit in öl wird durch Vermehrung der
aliphatischen Kohlenwasserstoffreste bewirkt.
Als M können auch Kondensationspolymere, z. B. lineare Polyamide und Polyester, verwendet werden.
Diese Polyamide und Polyester lassen sich nach bekannten Kondensationsreaktionen von polybasischen
Säuren, Polyaminen, mehrwertigen Alkoholen, Aminosäuren, Aminoalkoholen u. dgl. herstellen.
Den Schmierölen wird das beanspruchte Polyglykol in einer Menge von 0,1 bis 10 Gewichtsprozent,
vorzugsweise 1 bis 5 Gewichtsprozent, zugesetzt.
Als Schmieröle werden Mineralöle und synthetische öle verwendet.
Den Schmiermitteln können weitere andere übliche Schmierölzusätze, wie Mittel zur Herabsetzung des
Fließpunktes, Mittel zur Erhöhung der öligkeit, Hochdruckzusätze, Antioxydationsmittel, Korrosionsverhütungsmittel,
Eindickungsmittel und/oder Mittel zur Steigerung der Temperatur-Viskositäts-Eigenschaften
des Öls, zugesetzt werden.
Die folgenden Beispiele erläutern die Wirksamkeit der neuen Zusätze in den üblichen Asphaltversuchen.
Die Herstellung der Verbindungen wird hier nicht beansprucht.
Beim Asphaltversuch vermischt man 5 cm3 einer 5°/oigen Lösung des trockenen Polyglykol-Polymer-Zusatzes
mit 2 cm3 einer 1 %igen Lösung von luftgeblasenem Asphalt in Benzol und verdünnt dann
das Gemisch mit n-Pentan auf 25 cm3. Dieses verdünnte Gemisch wird geschüttelt und 2 Minuten
lang beobachtet. Wenn keine Koagulation eintritt, gibt man 2 cm3 Eisessig zu und notiert den Zeitpunkt,
in dem der Asphalt zu koagulieren beginnt. Die Ergebnisse des Asphaltversuchs stehen in Wechselbeziehung
zu der Kolbenverharzung und der Harzabscheidung für die Polyglykolzusätze. Erstarrungszeiten von 30 Minuten oder mehr zeigen, daß die
Dispergierungsmittel gute Wirkungen haben.
Dieses Beispiel zeigt die Mischpolymerisation von Dodecylmethacrylat und Polyäthylenglykol mit Methacrylamid
als Initiator.
Ausgangsgemisch:
112 g Dodecylmethacrylat (0,441 Mol),
8 g durch Methacrylamid zur Reaktion gebrachtes Polyäthylenglykol (Äquivalentgewicht 1100) (0,0072 Mol),
213 g Benzol.

Dieses Beispiel zeigt eine mit AHylamin als Initiator eingeleitete Mischpolymerisation von Dodecylmethacrylat
und Polyäthylenglykol (750 Molekulargewicht) zur Herstellung eines wirksamen Dispergierungsmittels.
Hierbei wurde nach dem gleichen Polymerisationsverfahren wie bei dem vorhergehenden Beispiel gearbeitet.
Die Beschickung bestand aus 40 g mit etwas AHylamin versetztem Polyäthylenglykol (750 Gewicht,
0,025 Mol), 20 g Dodecylmethacrylat (0,079 Mol) und 108 g Benzol. Der Katalysator bestand
aus 0,015% Azo-bis-isobutyronitril. Innerhalb von 5 Stunden gab man 60 g Dodecylmethacrylat
und 108 g Benzol zu. Die Polymerisation dauerte 8 Stunden, die Umwandlung betrug danach 82%.
Dem Reaktionsgemisch gab man sodann 100 g 150neutrales Mineralschmieröl zu und destillierte
dann das Benzol ab. Danach fügte man das dreifache Volumen gemischte Hexane zu, rührte das Gemisch
4 Stunden lang bei 54^C und ließ es über Nacht
stehen. Die unlöslichen Stoffe wurden zwecks Enttrübung des Gemisches durch Zentrifugieren abgeschieden.
Nach dieser Enttrübung war das Monomerenverhältnis 135 : 1. Der Asphaltversuch zeigte,
daß das Mischpolymere gute Dispergiereigenschaften hatte.
In einen 500 cm2-Dreihalskolben, der mit Rührwerk,
Rückflußkühler und Tropftrichter versehen war, gab man 100 g Dodecylmethacrylat (0,395 Mol),
20 g Polyäthylenglykol (Molekulargewicht 1600) — Vinyläther (0,011 Mol) und 0,01% Azo-bis-isobutyronitril,
blies den Kolben mit Stickstoff durch und polymerisiert^ bei Rückflußtemperatur. In Abständen
von 15 Minuten wurden kleine Mengen einer benzolischen Lösung von Azo-bis-isobutyronitril
zugesetzt, um den Katalysatorstand aufrecht-
zuerhalten. Die Umwandlung betrug innerhalb 8 Stunden 67 %. Eine Polyäthylenglykolanalyse
ergab ein Alkyl-Polyglykol-Verhältnis von 94 : 1.
Der Asphaltversuch dauerte mehr als 7 Stunden.
300 cm3 einer ll,6°/oigen Lösung von Polyisobutylen (Molekulargewicht etwa 200000) in Benzol
wurden mit 30 cm3 Phosphortrichlorid vermischt. Bei 10 bis 200C blies man dann Sauerstoff durch die
Lösung, bis die Wärmeentwicklung aufhörte, und reinigte dann das chlorphosphonylierte Polymere
durch wiederholtes Ausfallen aus Benzol mit Aceton. Die Ausbeute betrug 86%. 9 g dieses Produktes in
75 cm3 Benzol wurden 3 Stunden mit 5 cm3 Pyridin und 25 g getrocknetem, basenfreiem, mit etwas
Dodecyläther überdecktem Polyäthylenglykol (Molekulargewicht etwa 1800) am Rückflußkühler erwärmt.
Das auf diese Weise erhaltene Produkt wurde durch Ausfällen aus Benzol mit Methanol gereinigt.
10 g Polyisobutylen (Molekulargewicht etwa 000) und 0,25 g α,α'-Azo-bis-isobutyronitril wurden
in 150 cm3 Benzol gelöst und mit· Schwefeldioxydgas bei 60°C gesättigt. Das Gas wurde mit
l/Min, durch eine Frittenglasscheibe im unteren Teil des Gefäßes eingeführt; dann blies man Chlor
in einer Menge von etwa 1,25 l/Min. 10 Minuten lang durch ein Rohr oberhalb dieser Scheibe ein,
dann trockenen Stickstoff und gab schließlich die Lösung zu 25 g mit Dodecyläther überdecktem PoIyäthylenglykol
(Molekulargewicht etwa 1800) und cm3 Pyridin in 150 cm3 Chloroform. Das Geraisch
wurde vorsichtig eingeengt, bis das Volumen auf insgesamt 150 cm3 zurückgegangen war.
