  Verfahren zur Herstellung dem Kautschuk nahestehender Substanzen. 



   Es wurde bereits vorgeschlagen, elastische, dem natürlichen Kautschuk sehr nahestehende Substanzen in der Weise herzustellen, dass man Erythren (Divinyl) oder   .-T-Dimethyl-   butadien mit oder ohne Zusatz von   Verdünnungsmittein   oder katalytisch wirkenden Substanzen erwärmt. 



   Im weiteren Verfolg dieser technisch wertvollen Verfahren wurde die interessante   Beobachtung gemacht, dass   man ganz ähnliche Produkte erhält, wenn man statt Erythrenoder   -Y-Dirnethylbutadien   die   iibrigcu Homologen des Erythrons verwendet   und dass ganz generell Verbindungen vom Typus

 werden im Autoklaven während 12 Stunden auf 200  C erhitzt. Dann wird Wasserdampf zuletzt im Vakuum, solange durchgeleitet, bis alle Nebenprodukte entfernt sin. Auch hier resultiert eine kautschukähnliche Masse. 



   Beispiel 4. 



   Man verfährt wie im Beispiel 1, fügt jedoch zur Beförderung der   Polymerisation   5 Teile Amerisensäure hinzu und erhält gleichfalls eine elastische Masse.

  Process for the production of substances similar to rubber.



   It has already been proposed to produce elastic substances very similar to natural rubber in such a way that erythrene (divinyl) or.-T-dimethylbutadiene is heated with or without the addition of diluents or catalytically active substances.



   In the further pursuit of this technically valuable process, the interesting observation was made that very similar products are obtained if the remaining homologues of erythrone are used instead of erythrene or -Y-dirnethylbutadiene and that compounds of the type are generally used

 are heated to 200 C for 12 hours in an autoclave. Then steam is finally passed through in vacuo until all by-products are removed. Here, too, a rubber-like mass results.



   Example 4.



   The procedure is as in Example 1, but 5 parts of americic acid are added to promote the polymerization and an elastic mass is likewise obtained.



   Example 5.



   If the methylbutadiene in Example 1 is replaced by 500 parts of an erythrene derivative of the formula:
 EMI2.4
 
 EMI2.5
 Mass of rubber-like properties.



   Example6.



   100 parts of α-methylbutadiene are heated in a pressure bottle for a long time, e.g. B. three months in the incubator at about 55 C, then distilled under normal pressure

 Ah. The residue is dissolved in hot benzene. From this benzene solution fills. Alcohol is the same rubber-like substance as in Example 1.
 EMI2.7
 methylerythrene of the formula:
 EMI2.8
 be used. Likewise, other agents promoting the polymerization, such as e.g. B. Creosote etc. are used .. i '.. h the temperature can fluctuate within the broadest limits,
