Verfahren zur Beschleunigung der Autopolymerlaatlon von ss-#039-Dimethylerythren.
Im Journal für praktische Chemie, Band 64, Seite 109/10, hat Kondakow ein durch Autopolymerisation des ss-y-Dimethylerythrens erhaltenes Polymerisationsprodukt beschrieben.
Dieses Produkt ist, wie im Patente Nr. 49687 nachgewiesen wurde, von der nach den Angaben dieser Patentschrift durch Erwärmen des ss-#039-Dimethylerythrens erhältlichen kautschuk- ähnlichen Substanz vollständig verschieden.
Es wurde nun gefunden, dass sich die Polymerisation des -Dimethylerythrens zu dem von Kondakow beschriebenen Produkt dadurch wesentlich beschleunigen lässt, dass man die Reaktion unter Zusatz dieses Produktes ausführt. Das Produkt kann gemäss dem Verfahren des Patentes Nr. 59832 zur Herstellung eines Kautschuk-oder Guttaperchaersatzes dienen.
Beispiel :
100 Teile weisses Kondakowsches Produkt werden mit 300 Teilen von frisch dargestelltem -Dimethylerythren übergossen, das Gefäss % erschlossen und vor Licht geschützt stehen gelassen. Nach drei bis vier Wochen ist der Kohlenwasserstoff quantitativ in das weisse Kondakowsche Produkt übergegangen.
Es wurde hiebei noch die Beobachtung gemacht, dass die Einwirkung des Lichtes bel der Polymerisation durchaus nicht nötig ist, dass vielmehr die Polymerisation besser im
Dunkeln verläuft.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Method for accelerating the auto-polymer laatlon of ss- # 039-dimethylerythrene.
In the journal for practical chemistry, volume 64, page 109/10, Kondakow has described a polymerization product obtained by autopolymerization of ss-y-dimethylerythrene.
As demonstrated in patent no. 49687, this product is completely different from the rubber-like substance obtainable by heating the ss- # 039-dimethylerythrene according to the information in this patent specification.
It has now been found that the polymerization of -dimethylerythrene to the product described by Kondakow can be accelerated significantly by carrying out the reaction with the addition of this product. According to the method of patent no. 59832, the product can be used to produce a rubber or gutta-percha substitute.
Example:
100 parts of white Kondakov product are poured over 300 parts of freshly prepared -dimethyl erythrene, the vessel% opened and left to stand protected from light. After three to four weeks the hydrocarbon has been converted quantitatively into the white Kondakov product.
The observation was made that the action of light is by no means necessary for the polymerization, that the polymerization is better in the
Dark runs.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
