Die vorliegende Ausführungsform des Verfahrens gemäß Patentanmeldung F 23 041 IVb/39c liefert Kondensationsprodukte, deren Verträglichkeit mit und Löslichkeit in anderen aromatischen Komponenten erheblich verbessert ist. Besonders bei der Herstellung von Kondensationsprodukten von hohem Molekulargewicht empfiehlt sich zumindest die Mitverwendung von aromatischen Verbindungen der oben näher gekennzeichneten Konstitution.The present embodiment of the method according to patent application F 23 041 IVb / 39c provides condensation products, their compatibility with and solubility is vastly improved in other aromatic components. Especially with the Preparation of high molecular weight condensation products is recommended at least the use of aromatic compounds of those identified above Constitution.

Die als Ausgangsmaterial für die Umsetzung mit Aldehyden benötigten Ausgangsmaterialien können in bekannter Weise durch Einwirken von Alkylenoxyden auf aromatische sekundäre Amine, gegebenenfalls in Gegenwart basischer Katalysatoren, erhalten werden. Geeignete Oxalkylierungsmittel sind z. B. Äthylenoxyd, Propylenoxyd oder 1,2-Butylenoxyd. Je nach Dauer der Oxalkyherung erhält man Additionsprodukte aus 1 11o1 sekundärem Amin mit 2 und mehr Mol Alkylenoxyd. Vorteilhafte Ausgangsprodukte sind insbesondere die N-Mono-, Di-, Tri- und Tetraoxalkylierungsprodukte. An geeigneten sekundären Aminen seien die N-Äthyl-, N-Butyl- und N-Cyclohexylverbindungen des Anilins, Toluidins, Xylidins, 2,6-Diäthylanilins und Chloranilins genannt. Weitere zur Oxalkylierung geeignete Amine sind beispielsweise N,N'-Dimethyl-4,4'-diamino-dimethyldiphenylmethan, N-Methyl-a-bzw.-ß-Aminonaphthalin und N,N'-Dimethyl-1,8-diaminonaphthalin. Die Umsetzung dieser Ausgangsmaterialien mit Aldehyden geschieht in der in der Patentanmeldung F23041 IVb/39c angegebenen Verfahrensweise.The required as starting material for the reaction with aldehydes Starting materials can be prepared in a known manner by the action of alkylene oxides on aromatic secondary amines, optionally in the presence of basic catalysts, can be obtained. Suitable oxyalkylating agents are e.g. B. ethylene oxide, propylene oxide or 1,2-butylene oxide. Addition products are obtained depending on the duration of the oxyalkylation from 1 11o1 secondary amine with 2 or more moles of alkylene oxide. Advantageous starting products are in particular the N-mono-, di-, tri- and tetraoxalkylation products. At suitable secondary amines are the N-ethyl, N-butyl and N-cyclohexyl compounds of the Called aniline, toluidine, xylidine, 2,6-diethylaniline and chloroaniline. Further Amines suitable for oxalkylation are, for example, N, N'-dimethyl-4,4'-diamino-dimethyldiphenylmethane, N-methyl-α- or -β-aminonaphthalene and N, N'-dimethyl-1,8-diaminonaphthalene. The implementation these starting materials with aldehydes happens in the in the patent application F23041 IVb / 39c specified procedure.

Durch die Wahl des Mischungsverhältnisses der vorliegenden aromatischen Verbindungen mit denen der Hauptpatentanmeldung kann das Löslichkeitsverhalten der resultierenden Kondensationsprodukte in weiten Grenzen variiert werden.By choosing the mixing ratio of the aromatic present Compounds with those of the main patent application can affect the solubility behavior of the resulting condensation products can be varied within wide limits.

Die Verträglichkeit der Kondensationsprodukte mit anderen Materialien kann darüber hinaus durch Variation der am Stickstoff gebundenen Gruppe R' eingestellt werden. Mit steigender Kohlenstoffzahl der Gruppe R' steigt die Verträglichkeit des erhaltenen Kondensationsproduktes.The compatibility of the condensation products with other materials can also be adjusted by varying the group R 'bonded to the nitrogen will. The higher the carbon number of the group R ', the higher the compatibility of the condensation product obtained.

Die nach dem vorliegenden Verfahren erhältlichen niedrig- und höhermolekularen hydroxylgruppenhaltigen Kondensationsprodukte stellen demnach wertvolle Ausgangskomponenten zur Herstellung von Kunststoffen dar. Beispiel 1 Ein Gemisch von 538 g Tetraoxäthylanilin (2 Mol) und 151 g N-Methyl-oxäthylanilin (1 Mol) werden nach Zugabe von 100 g Paraformaldehyd unter Überleiten von Kohlendioxyd auf 80 bis 90°C erwärmt. Man setzt nun langsam 8 g Phosphorsäure zu, wobei eine schwach exotherme Reaktion eintritt und der Aldehyd allmählich in Lösung geht. Nach 1- bis 2stündiger Reaktionsdauer bei 80 bis 90°C wird allmählich Vakuum angelegt und so lange weiterkondensiert, bis kein Wasser mehr abdestilliert und die gewünschte Viskosität erreicht ist. Im vorliegenden Falle werden 25 ccm Wasser abgespalten. Das Kondensationsprodukt ist ein viskoses dunkles Öl, las eine OH-Zahl von 369 besitzt. Die Viskosität beträgt Q96 cP/75 ° C.The low and higher molecular weight ones obtainable by the present process Condensation products containing hydroxyl groups are therefore valuable starting components for the production of plastics. Example 1 A mixture of 538 g of tetraoxethylaniline (2 mol) and 151 g of N-methyl-oxäthylanilin (1 mol) are added after adding 100 g of paraformaldehyde heated to 80 to 90 ° C. while passing carbon dioxide over it. You are now betting slowly 8 g of phosphoric acid are added, a slightly exothermic reaction occurs and the aldehyde gradually goes into solution. After a reaction time of 1 to 2 hours at 80 to 90 ° C vacuum is gradually applied and condensation continues until there is no water more distilled off and the desired viscosity is reached. In the present case 25 ccm of water are split off. The condensation product is a viscous dark one Oil, read has an OH number of 369. The viscosity is Q96 cP / 75 ° C.

Beispiel 2 604 g N-Methyl-oxäthylanilin (4 Mol) und 140 g Paraormaldehyd werden allmählich auf 80 bis 90°C erwärmt ind 8 g Phosphorsäure zugegeben. Der Aldehyd geht allmählich in Lösung. Nach 1 bis 2 Stunden legt man ein chwaches Vakuum an und zieht das abgespaltene Wasser ib. Es werden 28 ccm Wasser abgespalten. Man erhält ein viskoses dunkles Öl mit einer O H-Zahl von 367.Example 2 604 g of N-methyl-oxäthylaniline (4 mol) and 140 g of para-formaldehyde are gradually heated to 80 to 90 ° C. and 8 g of phosphoric acid are added. The aldehyde gradually goes into solution. A weak vacuum is applied after 1 to 2 hours and draws off the water that has been split off. 28 cc of water are split off. You get a viscous dark oil with an OH number of 367.

Beispiel 3 538 g Tetraoxäthylanilin (2 Mol), 193 g N-Butyl->xäthylanilin (1 Mol) und 100 g Paraformaldehyd werden lach Zusatz von 8 g p-Toluolsulfonsäure auf 80 bis 90°C erwärmt. Sobald eine klare Lösung entstanden ist, legt nan allmählich Vakuum an und destilliert bei gleicher Cemperatur das entstandene Wasser ab. Es werden 23 ccm Wasser gebildet. Die O H-Zahl des resultierenden dunklen viskosen Öls beträgt 361.Example 3 538 g of tetraoxyethylaniline (2 mol), 193 g of N-butyl-> xethylaniline (1 mol) and 100 g of paraformaldehyde are added 8 g of p-toluenesulfonic acid heated to 80 to 90 ° C. As soon as a clear solution has emerged, nan lays down gradually Vacuum and the water formed is distilled off at the same temperature. It 23 cc of water are formed.
