Verfahren, die Elastizität der Vulkanisate künstlicher Kautschuksorten zu erhöhen.
Es wurde die bemerkenswerte Beobachtung gemacht, dass man die Elastizität künstlicher Kautschuksorten durch Beimischen vor der Vulkanisation von 10% und mehr öliger Körper, wie Petroleum, Leinöl, Ricinusöl, Paraffinöl, Hanföl, Safrol, Anilin, Alkylaniline, Xylidin, Dimethyl-p-toluidin usw. wesentlich verbessern kann. Es ist so möglich, jeden beliebigen auch vollkommen guten und vor Oxydation bereits geschützten künstlichen Kautschuk, der nicht sehr elastische Vulkanisate liefert, elastisch vulkanisierend zu machen.
Die erzielte Wirkung beruht darauf, dass man nicht wie nach den Angaben des D. R. P. Nr. 256413, zwecks Erzielung besserer Haltbarkeit des Kautschuks kleinere Mengen etwa 0'3%, sondern etwa in0/, und mehr der öligen Körper verwendet, die von den fertigen Gummigegenständen ganz aufgenommen werden. Durch diesen quantitativen Unterschied im Zusatz wird das Produkt qualitativ vollkommen verändert, und zwar so sehr, dass man von

100 Teile des von Kondakow im Journal für praktische Chemie, Band 64, Seite 109/no beschriebenen Polymerisationsproduktes des ss-y-Dimethylbutadiens werden auf der Walze mit 10 Teilen Schwefel, 2 Teilen Aldehydammoniak und 10 bis 25 Teilen Petroleum vermischt, zu einer Platte ausgezogen und dann 1/2 bis il/, Stunden vulkanisiert. Man erhält dann ein durchaus elastisches Produkt.
Beispiel 2.
Ersetzt man im obigen Beispiel das Kondakowsche Produkt durch ss-y-Dimethylbutadien- Kautschuk (Heisspolymerisat), so tritt eine ganz ähnliche Erscheinung auf,
Beispiel 3.
Ersetzt man im Beispiel i das Petroleum durch die gleiche Gewichtsmenge Safrol, so erhält man ebenfalls ein hochelastisches Vulkanisat.
Beispiel 4.
Wendet man an Stelle des Petroleums im Beispiel 1, 20 Teile Monomethylanilin an und erhitzt 30 Minuten auf vier Atmosphären, so zeichnet sich die vulkanisierte Klappe gleichfalls durch hohe Elastizität aus.
Die angewandten Mengen der obigen Substanzen können in weiten Grenzen schwanken.

Process to increase the elasticity of the vulcanizates of synthetic rubbers.
The remarkable observation was made that the elasticity of synthetic rubbers can be improved by adding 10% or more of oily substances, such as petroleum, linseed oil, castor oil, paraffin oil, hemp oil, safrole, aniline, alkylaniline, xylidine, dimethyl-p-toluidine, before vulcanization etc. can improve significantly. It is thus possible to make any artificial rubber that is perfectly good and already protected from oxidation and which does not provide very elastic vulcanizates, elastically vulcanizing.
The effect achieved is based on the fact that, in order to achieve better durability of the rubber, smaller amounts of about 0.3% are not used, as according to the information in DRP No. 256413, but about 0.5% and more of the oily bodies from the finished rubber objects be absorbed entirely. This quantitative difference in the additive completely changes the quality of the product, so much so that one of
EMI1.1
Example i.
100 parts of the polymerization product of ss-γ-dimethylbutadiene described by Kondakow in the Journal for Practical Chemistry, Volume 64, page 109 / no, are mixed on the roller with 10 parts of sulfur, 2 parts of aldehyde ammonia and 10 to 25 parts of petroleum and drawn out to a plate and then vulcanized 1/2 to 1 1/2 hours. A thoroughly elastic product is then obtained.
Example 2.
If, in the above example, the Kondakov product is replaced by ss-y-dimethylbutadiene rubber (hot polymer), a very similar phenomenon occurs,
Example 3.
If the petroleum is replaced in example i by the same amount of safrole by weight, a highly elastic vulcanizate is also obtained.
Example 4.
If, instead of the petroleum in Example 1, 20 parts of monomethylaniline are used and the mixture is heated to four atmospheres for 30 minutes, the vulcanized flap is also distinguished by its high elasticity.
The amounts of the above substances used can vary within wide limits.
