Description
Verfahren zur Darstellun' von polymerem Acrylsäurechlorid Es ist bekannt, Acrylsäurechlorid unter Einwirkung des Lichts zu polymerisieren. Es wurde nun gefunden, daß man diese Polymerisation außerordentlich beschleunigen kann, wenn man dem Acrylsäurechlorid kleine Mengen organischer basischer Körper, die in der Kälte nicht mit dem Acrylsäurechlorid reagieren, namentlich solcher, die auch als Vulkanisationsbeschleuniger wirksam sind, beispielsweise von Äthylenpolyamingemischen, d. h. Produkten, die durch Einwirkung von Ammoniak auf Dichloräthan erhältlich sind, Bipiperidyl, Aldehyd - Ammoniak - Kondensationsprodukten u. dgl. oder deren Gemischen, zusetzt. Die zur Polymerisation unter Einwirkung des Sonnenlichts erforderliche Zeit wird durch Zusatz derartiger Katalysatoren auf etwa 1/,3 verkürzt; im diffusen Tageslicht tritt unter Umständen überhaupt erst nach Zusatz dieser Stoffe eine Polymerisation ein. Beispiel ioo Teile reines Acrylsäurechlorid werden mit o, 5 Teilen Triäthylentetramin (vgl. B e i 1-stein, Handbuch der org. Chemie, IV. Auflage, Bd. q., S. 2¢9), die in ersterem ungelöst bleiben, versetzt und in einem gut gegen Luftfeuchtigkeit verschlossenen, nicht zu starkwandigen Glasgefäß 6i Stunden lang dem Sonnenlicht ausgesetzt. Ohne den Zusatzstoff benötigt die Polymerisation 18 und mehr Stunden einer Bestrahlung durch Sonnenlicht.Process for the preparation of polymeric acrylic acid chloride It is known Polymerize acrylic acid chloride under the action of light. It has now been found that you can accelerate this polymerization extremely if you use the acrylic acid chloride small amounts of organic basic bodies that do not react with the acrylic acid chloride in the cold react, especially those that are also effective as vulcanization accelerators are, for example, ethylene polyamine mixtures, d. H. Products by exposure from ammonia to dichloroethane are available, bipiperidyl, aldehyde - ammonia - Condensation products and the like or mixtures thereof. The one used for polymerization The time required under the action of sunlight is increased by the addition of such Catalysts shortened to about 1 /, 3; may occur in diffuse daylight Only after these substances have been added does a polymerisation occur. Example ioo parts pure acrylic acid chloride are mixed with 0.5 parts of triethylenetetramine (cf.B e i 1-stein, Org. Chemie, IV. Edition, Vol. Q., P. 2 [9), the first unsolved stay, displaced and in a well sealed against humidity, not Exposed to thick-walled glass vessels to sunlight for 6i hours. Without that The additive requires 18 and more hours of irradiation to polymerize Sunlight.
Man kann auch gewöhnliches Tageslicht oder künstliches Licht verwenden. An Stelle des obenerwähnten Triäthylentetramins kann man auch ein Gemisch von Aminen, wie es bei der Herstellung des vorgenannten Produktes erhalten wird, verwenden.Ordinary daylight or artificial light can also be used. Instead of the above-mentioned triethylenetetramine, you can also use a mixture of amines, as obtained in the manufacture of the aforementioned product, use.
Die Polymerisati3n verläuft auf diese Weise nahezu quantitativ. Das polymere Acrylsäurechlorid stellt eine klare, durchsichtige, zähe, elastische Masse dar, die sich an feuchter Luft oder in Wasser unter Salzsäureabspaltung mit einer weißen Haut überzieht. Es ist eüi wertvolles Zwischenprodukt, das beispielsweise zur Herstellung polymerer Acrylsäure, Acrylsäureester oder Acrylsäureamide Verwendung finden kann.The polymerisation proceeds almost quantitatively in this way. That polymeric acrylic acid chloride is a clear, transparent, tough, elastic mass which are in moist air or in water with elimination of hydrochloric acid with a covered with white skin. It is a valuable intermediate product, for example for the production of polymeric acrylic acid, acrylic acid esters or acrylic acid amides use Can be found.
