Description
Gegenstand der im nachstehenden beschriebenen Erfindung 1st ein Verfahren zur Herstellung von Schmierölzusätzen mit ausgezeichnetem Dispergiervermögen. FUr diesen Zweck 1st bereits eine große Reihe von Verbindungen vorgeschlagen, ohne daß bisher ein Produkt bekannt 1st, das allen Anforderungen hinsichtlich Wirksamkeit und Gestehimgekosten gerecht wird· Es ist bekannt« für den genannten Zweck brauchbare Produkte derart herzustellen» dafl polymerisierbar Verbindungen, deren Homopolymerisate in öl löslich sind, mit heterocyclischen Verbindungen mit einem tertiären Ringstickstoffatom, die eine polymerisierbar« Äthylendoppelbindung aufierhalb des Ringes« jedoch unmittelbar an diesem, aufweisen, mischpolyaierisiert werden. Als Beispiele für Monomere der eraXten Art selen vor allem Ester der Acrylsäure und Methacrylsäure, deren Alkoholrest mindestens 8, mit Vorteil 12 bis 16, C-Atome aufweist, ferner Vinylester organischer Säuren oder höhere Ester ungesättigter Dicarbonsäuren, wie Fumarsäure- und Itakonsäureester« genannt« - Monomere der zweiten Klasse Sind z· B, Vinylpyridine, Vinylpyrrolidine und Vinylpyrroll« done.The subject of the invention described below is a process for the production of lubricating oil additives with excellent Dispersibility. For this purpose is already proposed a large number of compounds without that so far a product is known that meets all requirements in terms of efficacy and cost of ownership, it is known that products that can be used for the stated purpose in this way to produce »that polymerisable compounds, their Homopolymers are soluble in oil, with heterocyclic Compounds with a tertiary ring nitrogen atom, the a polymerizable ethylene double bond on the outside Ring "but directly on this, have, mixed-polymerized will. As examples of monomers of the ancient kind selenium, especially esters of acrylic acid and methacrylic acid, the alcohol radical of which has at least 8, advantageously 12 to 16, carbon atoms has, furthermore vinyl esters of organic acids or higher esters of unsaturated dicarboxylic acids, such as fumaric acid and Itaconic acid esters "called" - monomers of the second class Are, for example, vinylpyridines, vinylpyrrolidines and vinylpyrroll « done.
Es 1st weiterhin bekannt, Schmierölzusätze derart herzustellen, daß das ein tertiäres Stickstoffatom aufweisende Monomere zu einem Zeltpunkt zu dem in Polymerisation beflndli-It is also known to produce lubricating oil additives in such a way that the monomer having a tertiary nitrogen atom has reached a point at which the polymer

Das Vorliegen von mindestens 15 %der Ausgangeverbindung in monomerer Form wird dabei als unerläßlich angesehen, da Pfropfpolymerisate, diechen monomers is given in which this is already polymerized to 40 to 85 % .

B. in der deutschen Auslegeschrift i 118 971 beschriebenen Produkte. Zu technisch besondere brauchbaren Schmierölzusätzen kommt man nach der genannten Druckschrift dann» wenn ein höherer Methacrylester innerhalb des bereits genannten Bereiches von 40 bis 85 % Umsatz polymerisiert wird* danach etwa δ Gew.-^ N-Vlnylpyrrolldon zugesetzt werden und das Ganze auspolymerislert wird.are obtained when the nitrogen-containing monomer is polymerized in the presence of the fully polymerized base product, have a worse effect in terms of compatibility and stability than the marked and z. B. in the German Auslegeschrift i 118 971 described products. According to the cited publication, technically particularly useful lubricating oil additives are obtained when a higher methacrylic ester is polymerized within the already mentioned range of 40 to 85% conversion * then about δ% by weight of N-vinylpyrrolldone is added and the whole is polymerized.
Es wurde gefunden« daß jenen Produkten, die bisher bereits als Schmierölzusätze, und zwar zur Verbesserung des VIskosltäts-Temperatur-Verhaltens und/oder zur Erniedrigung des Stockpunkte, vorgeschlagen worden sind, zusätzlich ein hohes Disperglervermögen verliehen werden kann, wenn polymerisierbar^ Verbindungen mit einem tertiären Stickstoffatom in Gegenwart solcher als Schmierölzusätze bereite bekannter Polymerisate bzw. Mischpolymerisate unter der Einwirkung radikaliseher Beschleuniger polymerisiert werden· Der angestrebte Effekt wird erreicht, wenn 2 bis 30 Gew.-# des pfropfend zu polymerisierenden, stickstoffhaltigen Monomeren, mit Vorteil 3 bis 4,5 Gew.-#, jeweils bezogen auf das Ausgangspolymerisat, zur Anwendung kommen· Mit besonderem Vorteil verwendet man dabei heterocyclische Stickstoffverbindungen, deren Stickstoffatom im Hing sitzt, während sich eine äthylenisch ungesättigte Gruppe außerhalb des Ringes, jedoch unmittelbar an diesem, befindet. Die Vorteile des neuen Verfahrens sind darin zu sehen, daß einmal alle bekannten VI-Verbeaserer hinsichtlich ihres Dispergiervermögens verbessert werden können und daß man zum anderen bei dem erfindungsgemäßen Vorgehen bei gleicher Wirksamkeit mit einen deutlich geringeren Anteil an stickstoffhaltigem Mononerem auskommt. Da die in der PraxisIt was found «that those products that have already been as lubricating oil additives, namely to improve the viscosity-temperature behavior and / or to reduce it of the pour points that have been proposed, additionally one high dispersing properties can be imparted if polymerizable compounds with a tertiary nitrogen atom are polymerized in the presence of such known polymers or copolymers, which are known as lubricating oil additives, under the action of radical accelerators. The desired effect is achieved when 2 to 30 wt .- # of the nitrogenous to be polymerized by grafting Monomers, with advantage 3 to 4.5 wt .- #, based in each case on the starting polymer are used · It is particularly advantageous to use heterocyclic nitrogen compounds whose nitrogen atom is in the ring, while an ethylenically unsaturated group is outside of the ring, but directly on it. the Advantages of the new method are to be seen in the fact that once all known VI verbeasers with regard to their Dispersibility can be improved and that one on the other hand in the procedure according to the invention with the same Effectiveness comes from a significantly lower proportion of nitrogen-containing monomers.

Methaorylsäurelorolester, sind die Gestehungskosten für die neuen Produkte niedriger als bei der Herstellung gleichwertiger Produkte im Wege der Mischpolymerisation. Im Vergleich zu hinsichtlich der Bruttozusammensetzung gleichen Produkten, die erhalten werden, wenn z. B. N-Vinyl-2-pyrrolidon auf einen bis zu einem Umsatz von 40 bis 85 % polymerisieren Methacrylsäurelerolester pfropfend polymerisiert wird, weist ein erfindungsgemäß hergestelltes Produkt ein vornehmlich im Dieselmotor sieh bemerkbar raachendesWenmutztrageverraügea auf.nitrogen-containing unsaturated compounds used, e.g. B. N-vinyl-2-pyrrolidone, are considerably more expensive than the monomers of the base polymer, e.g. B. Methaorylsäurelorolester, the production costs for the new products are lower than for the production of equivalent products by means of copolymerization. Compared to the same in terms of the gross composition products obtained when e.g. B. N-vinyl-2-pyrrolidone polymerized to a conversion of 40 to 85% methacrylic acid elerol ester is polymerized by grafting, a product produced according to the invention has a noticeably smudging wear and tear mainly in diesel engines.
Wenn es auch möglich ist, das neue Verfahren derart auszuführen, das ein hinsichtlich seiner Dispergierwirkung zu verbesserndes Basispolymerisat als Block- oder Emulsionspolymerisat hergestellt und dieses, gegebenenfalls nach vorheriger mechanischer Zerkleinerung, in dem stickstoffhaltigen Monomeren verteilt wird, geht man in aller Hegel so vor, das man die Ausgangsverbindung als Löeungspolymerisat in Ul herstellt, nach beendeter Polymerisation das stickstoffhaltige Monomere zugibt und dieses unter der Einwirkung eines geeigneten Radikalbildner» pfropfend polymerleiert.Even if it is possible to carry out the new process in such a way that the one with respect to its dispersing effect Improving base polymer prepared as a block or emulsion polymer and this, if necessary after mechanical comminution beforehand, in which nitrogen-containing monomers are distributed, is generally accepted so before that one prepares the starting compound as a solution polymer in Ul, after the end of the polymerization adding nitrogen-containing monomers and polymerizing this under the action of a suitable radical former »grafting.
