Description

Verfahren zur Herstellung von Kondensationsprodukten Es wurde gefunden, daß die in dem deutschen Patent 81o 814 angeführten Epoxydgruppen enthaltenden Verbindungen wertvolle Kondensationsprodukte ergeben, wenn sie mit Polycarbonsäureanhydriden umgesetzt werden. Die Produkte zeichnen sich durch gute Haftfähigkeit auf Glas, Metall usw. aus. Sie können vorteilhaft zu Verklebungen oder Überzügen oder Gießharzen usw. eingesetzt werden.Process for the production of condensation products It has been found that the compounds containing epoxy groups listed in German Patent 81o 814 result in valuable condensation products when mixed with polycarboxylic anhydrides implemented. The products are characterized by good adhesion to glass, Metal, etc. They can be beneficial to adhesives or coatings or casting resins etc. can be used.

Als Polycarbonsäureanhydride seien beispielsweise benannt: Phthalsäureanhydrid, Maleinsäureanhydrid, Addukte von Maleinsäureanhydrid an ungesättigte Verbindungen, wie z. B. Butadien usw. Selbstverständlich können auch Gemische von Anhydriden eingesetzt werden.Examples of polycarboxylic anhydrides are: phthalic anhydride, Maleic anhydride, adducts of maleic anhydride with unsaturated compounds, such as B. butadiene, etc. It is of course also possible to use mixtures of anhydrides will.

Die Anhydride können je nach Beschaffenheit der Epoxyverbindungen eingekugelt oder in die flüssigen oder aufgeschmolzenen Verbindungen eingerührt werden.The anhydrides can, depending on the nature of the epoxy compounds balled or stirred into the liquid or melted compounds will.

Die Reaktion vollzieht sich in Abhängigkeit der angewandten Temperatur verschieden schnell. Oft ist es am einfachsten, das Anhydrid oberhalb seiner Schmelztemperatur in die Epoxydverbindungen einzurühren. Die molare Menge an Anhydrid soll die Molzahl noch freier Epoxydgruppen nicht wesentlich übersteigen; in den meisten Fällen wird sie darunterliegen, um die Alkalifestigkeit der Reaktionsprodukte nicht zu verschlechtern.The reaction takes place depending on the temperature used at different speeds. It is often easiest to keep the anhydride above its melting temperature stir into the epoxy compounds. The molar amount of anhydride is said to be the number of moles as yet free epoxy groups are not essential exceed; in most In some cases, it will be lower in order to reduce the alkali resistance of the reaction products to deteriorate.

Die Reaktion kann jederzeit unterbrochen und an beliebiger Stelle weitergeführt werden. Wird das ankondensierte Produkt beim Erkalten hart, so kann es pulverisiert und dann als Pulver auf heiße Metallplatten aufgestreut werden. Die Platten können auf diese Weise verklebt werden.The reaction can be interrupted at any time and at any point to be continued. If the condensed product becomes hard when it cools, it can it can be pulverized and then sprinkled as a powder on hot metal plates. The panels can be glued in this way.

Beispiel zo g der Epoxydverbindung aus Toluoldisulfosäurebis-methylamid und Epichlorhydrin werden bei 14o° mit 4 9 Phthalsäureanhydrid verrührt und die homogene Mischung auf eine Glasplatte gestrichen. Nach 3stündigem Erhitzen auf 14o° ist ein in der Kälte festhaftender harter Film entstanden.Example zo g of the epoxy compound from Toluoldisulfosäurebis-methylamide and epichlorohydrin are stirred at 14o ° with 4 9 phthalic anhydride and the homogeneous mixture onto a glass plate deleted. After heating at 140 ° for 3 hours, a hard film that adheres firmly in the cold has formed.
