Patentiert im Deutschen Reiche vom 8. August 1911 ab.Patented in the German Empire on August 8, 1911.

Im Journal für praktische Chemie, Band 64, S. 109/110, hat Kondakow ein durch Autopolymerisation des ß-y-Dimethylerythrens erhaltenes Polymerisationsprodukt beschrieben. Dieses Produkt ist, wie wir im Patent 250335 nachgewiesen haben, von der nach den Angaben dieses Patentes durch Erwärmen des ß-y-Dimethylbutadiens erhältlichen kautschukähnlichen Substanz vollständig verschieden.In the Journal of Practical Chemistry, Volume 64, pp. 109/110, Kondakov has a through autopolymerization of the ß-γ-dimethylerythrene obtained polymerization product described. As we have demonstrated in patent 250335, this product is different from the information given of this patent by heating the ß-γ-dimethylbutadiene rubber-like obtainable Substance completely different.

Es stellt eine weiße, krümelige Masse dar, die sich an der Luft so schnell verändert, daß sie sich auf der Walze nur dann zu einem Fell verarbeiten läßt, wenn sie diesem Prozeß gleich nach ihrer Gewinnung unterworfen wird. Die so hergestellten Felle sind aber ebenfalls nur sehr kurze Zeit haltbar und verharzen schnell an der Luft, so daß sie für die technische Verwertung überhaupt nicht in Frage kommen.It is a white, crumbly mass that changes so quickly in the air that it changes can only be processed into a skin on the roller if it is the same as this process is subjected after its extraction. The skins produced in this way are also only very short time and resinify quickly in the air, so that they are suitable for technical Recovery are out of the question at all.

Es wurde nun gefunden, daß sich dieseIt has now been found that this

ao Substanz in ein haltbares und technisch sehr vorteilhaftes, als Kautschuk- oder Guttaperchaersatz brauchbares Produkt umwandelt, wenn man sie der Einwirkung basisch reagierender Substanzen aussetzt.ao substance in a durable and technically very advantageous, as a rubber or gutta-percha substitute converts usable product when exposed to the action of alkaline substances.

Beispiel.Example.

ioo Teile des von Kondakow beschriebenen weißen Polymerisationsproduktes des ß-y-Dimethylerythrens werden in iooo Teile 2 pro- ■ zentiges Anilin wasser gelegt und 24 Stunden darin mazeriert. Durch Pressen auf der Walze erhält man aus dem so vorbehandelten Produkt ein gleichmäßiges gut haltbares Fell.100 parts of the white polymerization product of β-γ-dimethylerythrene described by Kondakow 2 percent aniline water is placed in iooo parts and 24 hours macerated in it. The pretreated product is obtained by pressing on the roller an even, durable coat.

Statt Anilin kann man in ähnlicher Weise auch andere basische Körper, wie Ammoniak, Dimethylamin, Diäthylamin, Natronlauge oder ähnliche, verwenden.Instead of aniline, you can use other basic bodies in a similar way, such as ammonia, Use dimethylamine, diethylamine, caustic soda or similar.
