Description
<Desc/Clms Page number 1>
Verfahren zur Beschleunigung und Vervollständigung der Polymerisation des In Kautschuk oder kautschuklhnllche Substanzen überzuführenden Butadiens bzw. 8einer Homologen.
EMI1.1
Man fügt zu 100 Teilen der kautschukartigen Masse, die mit Hilfe von Natrium aus Butadien erhalten worden ist, 100 Teile durch Abkühlung verflüssigtes Butadien und überlässt die Masse sich selbst. Nach einiger Zeit ist quantitative Polymerisation erfolgt.
Beispiel 2.
EMI1.2
bewahrt, polymerisiert die Mischung nach einiger Zeit quantitativ zur kauthukartigon Masse.
B e i s p i e l 3.
Zu 1000 Teilen des durch Polymerisieren von ss-#-Dimethylbutadien erhaltenen Produkts gibt man 1000 Teile Dimethylbutadien. Der Kohlenwasserstoff wird \ ig von dem Kautschuk aufgesaugt. Man erwärmt nun die Masse vier Wochen lang in geschlossenem Gefäss auf 70" ; nach dieser Zeit ist der Kohlenwasserstoff verschwunden und man erhält ausschliesslich die kautschukartige Substanz.
An Stelle der In den Beispielen genannten kautschukartigen Massen können andere Homologen und analoge Kautschuke oder Gemische derselben Verwendung finden.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for accelerating and completing the polymerization of butadiene or homologues to be converted into rubber or rubber-like substances.
EMI1.1
100 parts of the rubber-like mass, which has been obtained from butadiene with the aid of sodium, are added to 100 parts of butadiene liquefied by cooling and the mass is left to stand. After some time, quantitative polymerization has taken place.
Example 2.
EMI1.2
preserved, the mixture polymerizes quantitatively to the chewable mass after some time.
Example 3.
1000 parts of dimethylbutadiene are added to 1000 parts of the product obtained by polymerizing ß - # - dimethylbutadiene. The hydrocarbon is absorbed by the rubber. The mass is now heated to 70 "in a closed vessel for four weeks; after this time the hydrocarbon has disappeared and only the rubber-like substance is obtained.
Instead of the rubber-like compositions mentioned in the examples, other homologues and analogous rubbers or mixtures thereof can be used.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
