Description

Beispiel 3.Example 3.

Ersetzt man in dem vorstehenden Beispiel 2 den Aldehydammoniak durch Natriumamid, erreicht man dasselbe Resultat. g0 If in the above example 2 the aldehyde ammonia is replaced by sodium amide, the same result is achieved. g 0

Ebenso kann man andere der genannten Basen, wie Benzylamin, Naphtylendiamine, quaternäre Ammoniumbasen, verwenden.You can also use other of the bases mentioned, such as benzylamine, naphthylenediamines, use quaternary ammonium bases.

Verfahren zur Beschleunigung der Vulkanisation von natürlichen oder künstlichen Kautschukarten bzw. des von Ko η dakow im Journal für praktische Chemie Bd. 64, S. 109/110 beschriebenen Polymerisationsprodukts aus ß-y-Dimethylbutadien, dadurch gekennzeichnet, daß man den zu vulkanisierenden Massen basisch reagierende Ammoniakderivate bzw. solche Basen zusetzt, deren Dissoziationskonstante größer als etwa 1 X io~8 ist.Process for accelerating the vulcanization of natural or synthetic rubbers or of the polymerization product of β-γ-dimethylbutadiene described by Ko η dakow in the Journal for Practical Chemistry Vol. 64, p. 109/110, characterized in that the masses to be vulcanized are basic Reacting ammonia derivatives or bases are added whose dissociation constant is greater than about 1 × 10 ~ 8 .

Claims (1)

Patent-Anspruch :Patent claim: Beispiel 2.Example 2. 100 Teile Parakautschuk werden mit 10 Teilen Schwefel und 1 Teil Aldehydammoniak gemischt und eine halbe Stunde auf 3 Atmosphären erhitzt. Das Material ist vollkommen ausvulkanisiert, während es ohne diesen Zusatz etwa die vierfache Zeit hierzu benötigt hätte.100 parts of para rubber are mixed with 10 parts Sulfur and 1 part aldehyde ammonia mixed and half an hour to 3 atmospheres heated. The material is completely vulcanized while it is without this addition it would have taken about four times as long to do this.
