  Verfahren zur Darstellung einer dem Kautschuk nahestehenden Substanz. 



   Es wurde die technisch sehr wichtige Beobachtung gemacht, dass man zu einer dem Kautschuk nahestehenden Substanz gelangt, wenn man Erythren (Divinyl) mit oder ohne Zusatz von die Polymerisation befördernden Mitteln, wie Essigsäure, Essigsäureanhydrid und   Natriumäthylat,   und zwar zweckmässig in Mengen von 1/2 bis   50/0   erwärmt, wobei die Temperatur innerhalb weiter Grenzen schwanken kann. 



   Beispiel 1. 



   500 Teile   Erythret) werden   in Benzol gelöst und die so erhaltene Lösung im Autoklaven 10 Stunden auf 1500 erhitzt. Durch Durchleiten von Wasserdampf wird hierauf das Benzol sowie etwa entstehende Nebenprodukte abgetrieben. Es hinterbleibt eine elastische, delll natürlichen Kautschuk sehr ähnliche Substanz. 



   Beispiel 2. 



   200 Teile Erythren worden durch Abkühlen, z. B. mit Hilfe von   Ätherkohlensäure,     verdichtet.   Die so erhaltene farblose   Flüssigkeit   wird dann im Autoklaven 4 Tage lang auf   ')   0 bis 100  erhitzt. Das nicht polymerisierte Erythren wird abdestilliert und der Rückstand sodann im Vakuum auf dem Wasserbade (zuletzt auf dem siedenden Wasserbade) noch einige Zeit erwärmt. Es destilliert eine der Terpenreihe angehörende   Flüssigkeit über,   wahrend eine elastische, dem Kautschuk sehr ähnliche Masse hinterbleibt.

  Process for the preparation of a substance closely related to rubber.



   The technically very important observation was made that a substance similar to rubber is obtained if erythrene (divinyl) is added with or without the addition of agents that promote the polymerization, such as acetic acid, acetic anhydride and sodium ethylate, expediently in amounts of 1 / 2 to 50/0 heated, whereby the temperature can fluctuate within wide limits.



   Example 1.



   500 parts of Erythret) are dissolved in benzene and the solution obtained in this way is heated to 1500 in an autoclave for 10 hours. The benzene and any byproducts formed are then driven off by passing steam through. What remains is an elastic substance very similar to natural rubber.



   Example 2.



   200 parts of Erythren have been made by cooling, e.g. B. with the help of ether carbonic acid, compressed. The colorless liquid thus obtained is then heated to 0 to 100 for 4 days in an autoclave. The unpolymerized erythrene is distilled off and the residue is then heated in vacuo on the water bath (lastly on the boiling water bath) for some time. A liquid belonging to the terpene series distills over, while an elastic mass, very similar to rubber, remains behind.
