Description

Verfahren zur Herstellung harz- oder kautschukartiger Stoffe Gegenstand des Patents 727 116 ist ein Verfahren zur Herstellung harzartiger, insbesondere als Schmierölverbesserungsmittel geeigneter Verbindungen, nach welchem man ungesättigte Kohlenstoffverbindungen auf einen Kohlenstoffring enthaltende harzartige Stoffe in Gegenwart von Lösungsmitteln, die im wesentlichen aus Chlorkohlenwasserstoffen oder chlorierten Äthern bestehen, unter Vermittlung von Borfluorid oder einer mit Fluorverbindungen behandelten Bleicherde einwirken läßt. Nach dem Zusatzpatent 907 7o2 kann man hierbei auch Gemische von einfach und mehrfach ungesättigten Kohlenstoffverbindungen verwenden.Process for the production of resinous or rubber-like substances The subject of patent 727 116 is a process for the production of resin-like compounds, particularly those suitable as lubricating oil improvers, according to which unsaturated carbon compounds are deposited on a carbon ring-containing resinous substances in the presence of solvents, which essentially consist of chlorinated hydrocarbons or chlorinated ethers exist, with the mediation of boron fluoride or a bleaching earth treated with fluorine compounds can act. According to the additional patent 907 702, mixtures of monounsaturated and polyunsaturated carbon compounds can also be used here.

Es wurde nun gefunden, daB man bei diesen Verfahren als Lösungsmittel auch flüssige nitrierte aromatische Verbindungen, z. B. Nitrobenzol oder Nitrotoluol, verwenden kann.It has now been found that the solvent used in these processes also liquid nitrated aromatic compounds, e.g. B. nitrobenzene or nitrotoluene, can use.

Beispiel In einer Lösung von 33 Gewichtsteilen Polystyrol (mittleres Molgewicht etwa 80 ooo) und b7 Gewichtsteilen Paraffinspaltprodukt in 75 Gewichtsteilen Nitrobenzol wird bei Zimmertemperatur 7 Stunden Borfluorid eingeleitet. Die dabei entstehende zähflüssige Masse wird in z8o Gewichtsteilen Maschinenöl (Viskosität 6,5° E bei 5o3) gelöst und bei 23o° so lange mit überhitztem Wasserdampf behandelt, bis kein Nitrobenzol mehr übergeht. Man erhält etwa 27o Gewichtsteile einer zähen Masse, die etwa 33 °/a Polyalkylstyrol enthält. Setzt man zu einem Maschinenöl mit einer Viskosität von z,65° E bei 99° und einem Viskositätsindex von 50 3 °/o dieses Produktes zu, so wird die Viskosität auf 2,i5° E bei 99° und der Viskositätsindex auf 9o erhöht.EXAMPLE Boron fluoride is passed in for 7 hours at room temperature into a solution of 33 parts by weight of polystyrene (average molecular weight about 80,000) and b7 parts by weight of paraffin cleavage product in 75 parts by weight of nitrobenzene. The resulting viscous mass is dissolved in 80 parts by weight of machine oil (viscosity 6.5 ° E at 503) and treated with superheated steam at 230 ° until no more nitrobenzene passes over. About 270 parts by weight of a viscous mass are obtained which contain about 33% polyalkylstyrene. If this product is added to a machine oil with a viscosity of z.65 ° E at 99 ° and a viscosity index of 50 3%, the viscosity is increased to 2.15 ° E at 99 ° and the viscosity index is increased to 9o.
