  Verfahren zur Darstellung von Kautschuk und   kaut8chukihnllchen   Substanzen. 



   Durch das Stammpatent Nr. 54720 ist ein Verfahren geschützt, Butadien. seine Homologen und Analogen dadurch in dem Kautschuk nahestehende Substanzen   überzuführen.   dass man diese Kohlenwasserstoffe der Einwirkung der Metalle der Alkali-oder Erdalkalireihe, ihrer Mischungen, Legierungen und Amalgame aussetzt. 



   Es wurde nun gefunden, dass die Polymerisation leichter vor sich geht und man einen in der Qualität gleichmässigeren   Kautschuk erhält, wenn   man ein Natrium zur Reaktion verwendet. das mit einer Oxydschicht überzogen ist. 



   Beispiel :
1000 Teile Isopren werden mit 20 Teilen Natriumdraht versetzt, der vorher solange der 
 EMI1.1 
 man die Vorbehandlung des Natriumdrahtes, so dauert die   Polymerisation länger und liefert   ein weniger nerviges Produkt. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the preparation of rubber and chewable substances.



   A process, butadiene, is protected by the parent patent no. 54720. thereby converting its homologues and analogues into substances closely related to rubber. that these hydrocarbons are exposed to the action of the metals of the alkali or alkaline earth series, their mixtures, alloys and amalgams.



   It has now been found that the polymerization proceeds more easily and that the quality of the rubber is more uniform if a sodium is used for the reaction. which is coated with an oxide layer.



   Example:
1000 parts of isoprene are mixed with 20 parts of sodium wire, which was previously as long as the
 EMI1.1
 If you pretreat the sodium wire, the polymerization takes longer and provides a less annoying product.

Claims (1)

An Stelle des im Beispiel genannten Isopren lassen sich andere Butadiene verwenden ; ebenso können die Butadiene mit indifferenten Lösungsmitteln versetzt werden. An Stelle von EMI1.2 PATENT-ANSPRTJCH : Verfahren zur Darstellung von Kautschuk und kautschukähnlichen Substanzen, dadurch gekennzeichnet, dass man Butadien, seine Homologen und Analogen der Einwirkung oberfiächlieh oxydierter Leichtinetalle aussetzt. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. Instead of the isoprene mentioned in the example, other butadienes can be used; Indifferent solvents can also be added to the butadienes. Instead of EMI1.2 PATENT APPLICATION: Process for the preparation of rubber and rubber-like substances, characterized in that butadiene, its homologues and analogs are exposed to the action of superficially oxidized light metals. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
