Zusatz zum Patent 250920.Addition to patent 250920.

Patentiert im Deutschen Reiche vom 1. November 1911 ab. Längste Dauer: 7. August 1926.Patented in the German Empire on November 1, 1911. Longest duration: August 7, 1926.

Durch das Patent 250920 ist ein Verfahren zur Darstellung eines technisch wertvollen, als Kautschukersatz brauchbaren Produkts geschützt, das darin besteht, daß man das von Kondakow im Journal für praktische Chemie, Bd. 64, S. 109,110 beschriebene Polymerisationsprodukt aus ß-y-Dimethylerythren mit alkalischen Mitteln behandelt.The patent 250920 describes a method for the production of a technically valuable, product usable as a rubber substitute, which consists in that one Polymerization product described by Kondakow in the Journal of Practical Chemistry, Vol. 64, pp. 109,110 from ß-y-dimethylerythrene treated with alkaline agents.

Es wurde nun gefunden, daß man direkt zu einem brauchbaren Material gelangt, das keiner weiteren Bearbeitung mehr bedarf, wenn man die alkalischen Mittel schon bei der Bildung des genannten Polymerisationsprodukts anwendet. Selbstverständlich kann man auch hier die Polymerisation unter Zusatz des fertigen Produkts gemäß dem Verfahren unseres Patents 254371 ausführen, wobei man zweckmäßig von vornherein schon bei Gegenwart der alkalischen Mittel gewonnenes Polymerisationsprodukt verwendet. Das so erhaltene Produkt kann ebenso wie das nach dem Hauptpatent 250920 erhältliche nach dem Verfahren des Patents 255680 vulkanisiert werden.It has now been found that one arrives directly at a useful material that no further processing is required if the alkaline agents are already used in the Formation of said polymerization product applies. Of course you can too here the polymerization with the addition of the finished product according to our method Execute patent 254371, whereby one expedient from the start with the present The polymerization product obtained from the alkaline agent is used. The thus obtained Product, like that obtainable under main patent 250920, can be vulcanized using the method of patent 255680 will.

Das vorliegende Verfahren betrifft die Behandlung des schon fertig gebildeten Produkts und hat mit dem Polymerisationsvorgang selbst nichts zu tun. Die Polymerisation verläuft gerade so, als wenn die Base nicht vorhanden wäre. Ihr Einfluß erstreckt sich nur auf das fertige Produkt, das haltbar wird. Es wird hierbei ein anderes Produkt erhalten als durch Polymerisation des ß-y-Dimethylerythrens in der Wärme. Der bei letzterem Verfahren angewandte Zusatz von alkalischen Reagenzien hat hierbei lediglich den Zweck, die Bildung von Nebenprodukten bei der Polymerisation einzuschränken.The present method relates to the treatment of the already formed product and has nothing to do with the polymerization process itself. The polymerization proceeds just as if the base weren't there. Their influence only extends on the finished product that will last. Another product is obtained here than by polymerization of ß-γ-dimethylerythrene in the heat. The one with the latter The addition of alkaline reagents used in the process has the sole purpose of limit the formation of by-products during the polymerization.

Beispiel 1.Example 1.

1000 Teile ß-y-Dimethylerythren werden mit 5 Teilen Anilin versetzt und der Autopolymerisation überlassen. Das nach einiger Zeit gebildete weiße kautsckukartige Produkt ist haltbar und läßt sich gut vulkanisieren.1000 parts of ß-y-dimethylerythrene are with 5 parts of aniline were added and left to self-polymerize. After a while The white rubber-like product formed is durable and can be vulcanized well.

Beispiel 2.Example 2.

4545

1000 Teile ß-y-Dimethylerythren werden mit 300 Teilen des nach Beispiel 1 erhaltenen Polymerisationsprodukts und 3,5 Teilen Dimethylanilin versetzt. Nachdem man das Material etwa vier Wochen sich selbst überlassen hat, ist die Masse quantitativ in einen gut haltbaren Kautschukersatz übergegangen. Beim Vulkanisieren liefert derselbe eine gute Platte.1000 parts of ß-y-dimethylerythrene are with 300 parts of the polymerization product obtained in Example 1 and 3.5 parts of dimethylaniline offset. After leaving the material to itself for about four weeks, is the mass converted quantitatively into a durable rubber substitute. When vulcanizing it makes a good record.

Statt Anilin oder Dimethylanilin können andere basische Körper, wie Ammoniak, Dimethylamin, Diäthylamin, Natronlauge oderInstead of aniline or dimethylaniline, other basic substances such as ammonia, dimethylamine, Diethylamine, caustic soda or

ähnliche verwendet werden, auch können die Mengenverhältnisse an Kohlenwasserstoff und Base andere sein.Similar can be used, and the proportions of hydrocarbons and Base be other.

Patent-Anspruch :Patent claim: Abänderung des durch die Patente 250920 und 254371 geschützten Verfahrens zur Darstellung eines technisch wertvollen, als Kautschukersatz brauchbaren Produkts, darin bestehend, daß man, anstatt das von Kondakow im Journal für praktische Chemie, Bd. 64, S. 109/110 beschriebene Polymerisationsprodukt aus ß-y-Dimethylerythren mit alkalischen Mitteln zu behandeln, hier die Behandlung mit alkalisehen Agenzien schon während der Polymerisation bei einer Temperatur von nicht mehr als 40 ° ausführt.Modification of the method of representation protected by patents 250920 and 254371 of a technically valuable product which can be used as a rubber substitute, consisting in the fact that, instead of that of Kondakow in the Journal for Practical Chemistry, Vol. 64, pp. 109/110 To treat the polymerization product of ß-y-dimethyl erythro with alkaline agents, here the treatment with alkaline agents already during the polymerization performs at a temperature not exceeding 40 °.
