Description
Polymerisationsprodukte aus trocknenden ölen und Styrol sind bereits bekannt. Bei der Herstellung dieser Produkte verwendet man im Hinblick auf die Verwendung als Lackrohstoff flüchtige Lösungsmittel. Es wurde nun gefunden, daß man für gewisse Verwendungszwecke besonders geeignete Polymerisationsprodukte erhält, wenn man trocknende öle oder deren Abwandlungsprodukte, soweit sie noch reaktionsfähige Doppelbindungen besitzen, mit Arylolefinen in Gegenwart von Alkylbenzolen mit mindestens etwa 8 C-Atomen in der Seitenkette polymerisiert. Polymerization products made from drying oils and styrene are already known. In the preparation of With a view to their use as paint raw materials, volatile solvents are used for these products. It has now been found that polymerization products which are particularly suitable for certain uses can be obtained obtained when drying oils or their modification products, insofar as they still exist Have reactive double bonds with aryl olefins in the presence of alkylbenzenes with at least polymerized about 8 carbon atoms in the side chain.
Geeignete trocknende Öle sind z. B. Ricinenöl, Holzöl, isomerisiertes Leinöl usw.; geeignete Ab-Suitable drying oils are e.g. B. ricin oil, wood oil, isomerized linseed oil, etc .; suitable ab-
wändlungsprodukte sind die aus trocknenden ölen oder den ihnen zugrunde liegenden Fettsäuren, zweibasischen Carbonsäuren, insbesondere Phthalsäure, und mehrwertigen Alkoholen, z. B. Glycerin, Pentaerythrit usw., erhältlichen Kondensationsprodukte. Unter Arylolefinen werden vorzugsweise Benzole mit einer ao ungesättigten Seitenkette, ζ. B. Styrol, Methylstyrol, Vinylnaphthalin usw., verstanden. Als Alkylbenzole kommen insbesondere solche Mono- oder Polyalkylbenzole in Betracht, wie sie als Ausgangsmaterial für die Herstellung von Waschrohstoffen verwendet werden, oder auch solche, die bei der Fraktionierung von für Waschrohstoffe vorgesehenen Alkylbenzolen als Nachlauf anfallen.Modification products are those made from drying oils or the underlying fatty acids, dibasic carboxylic acids, especially phthalic acid, and polyhydric alcohols, e.g. B. glycerol, pentaerythritol, etc., available condensation products. Under Aryl olefins are preferably benzenes with an ao unsaturated side chain, ζ. B. styrene, methyl styrene, Vinyl naphthalene, etc., understood. Particularly suitable alkylbenzenes are mono- or polyalkylbenzenes into consideration of how it is used as a raw material for the manufacture of laundry raw materials or those used in the fractionation of alkylbenzenes intended for detergent raw materials incurred as overrun.
Die Polymerisationsprodukte werden erhalten, indem man z. B. die trocknenden öle in der 1Z2- bis iVgfachen Menge eines Alkylbenzole mit mindestens 8 C-Atomen in der Seitenkette auflöst, diese Lösung sodann mit der 1Z2- bis ifachen Gewichtsmenge an Arylolefinen, bezogen auf die Gewichtsmenge der trocknenden öle, mischt und das Gemisch in an sich bekannter Weise polymerisiert. Gegebenenfalls kannThe polymerization products are obtained by e.g. B. dissolves the drying oils in the 1 Z 2 - to iVgfache amount of an alkylbenzenes with at least 8 C-atoms in the side chain, then this solution with the 1 Z 2 - to twice the weight of aryl olefins, based on the weight of the drying oils, mixes and polymerizes the mixture in a manner known per se. If necessary, can
man die rascher polymerisierende Komponente, d. h. das Arylolenn, auch allmählich mit dem Fortschreiten der Polymerisation zugeben. Besonders vorteilhaft ist es, in Abwesenheit von Polymerisationsbeschleunigern oder -verzögerern zu arbeiten und durch längeres Erhitzen auf Temperaturen von 140 bis 200° zu polymerisieren.the more rapidly polymerizing component, d. H. the aryl olene, also gradually as it progresses add to the polymerization. It is particularly advantageous in the absence of polymerization accelerators to work or retarders and by prolonged heating to temperatures of 140 to To polymerize at 200 °.

mittel bei der Polymerisation von trocknenden Ölen mit Arylolefinen gelingt es, die Arylolefine in erheblichen Anteilen einzupolymerisieren, ohne daß die erhaltenen Produkte gelieren, feste Bestandteile ausscheiden oder eine unerwünscht hohe Viskosität besitzen bzw. im Verlauf der Zeit annehmen. Die erhaltenen Produkte zeichnen sich durch ihre Klarheit aus und sind wertvolle Rohstoffe für die anwendungstechnische Industrie, vorzugsweise für die Lack- und Druckfarbenindustrie.medium in the polymerization of drying oils with aryl olefins, the aryl olefins succeed in considerable To polymerize proportions without the products obtained gelling, solid constituents separate out or have an undesirably high viscosity or assume over time. the The products obtained are characterized by their clarity and are valuable raw materials for application technology Industry, preferably for the paint and printing ink industry.

Anschließend wird im Verlauf von weiteren 26 Stunden allmählich auf 2000 erhitzt. Man erhält eine homogene, klare und viskose Lösung, welche nur noch eine geringfügige Menge monomeres Styrol1000 parts of styrene are allowed to run in at 140 ° to 160 ° over a period of about 10 hours with stirring to a solution of 1000 parts of medium viscosity ricin stand oil in 1000 parts of technical-grade undecylbenzene. The mixture is then heated in the course of a further 26 hours gradually to 200 0th A homogeneous, clear and viscous solution is obtained which only contains a small amount of monomeric styrene
