KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Durch Patent 255680 ist ein Verfahren zur Darstellung eines dem vulkanisierten Kautschuk nahestehenden Produkts geschützt, welches darin besteht, daß man das durch Einwirkung von basischen Agenzien auf das von Kondakow im Journal für praktische Chemie, Bd. 64, S. 109/110, beschriebene Polymerisationsprodukt des ß-y-Dimethylbutadiens erhältliche Produkt vulkanisiert.By patent 255680 is a method of making one of the vulcanized rubber related product protected, which consists in the fact that you can do this through action of basic agents to the polymerization product described by Kondakow in the Journal for Practical Chemistry, Vol. 64, pp. 109/110 of the ß-γ-dimethylbutadiene available product vulcanized.
Es wurde nun gefunden, daß bei Verwendung von Piperidin oder seinen Homologen als basische Agenzien besonders guter Hartgummi entsteht. Bemerkenswert ist hierbei, daß man auch bei den Vulkanisationsverfahren, die sonst zum Weichgummi führen, hier einen Hartgummi erhält.It has now been found that when using piperidine or its homologues Particularly good hard rubber is produced as a basic agent. It is noteworthy that that one also has one here with the vulcanization processes that otherwise lead to soft rubber Hard rubber receives.
100 Teile Kondakowsches Produkt werden 20- mit 0 J75 Teilen Piperidin auf der Walze gemischt, während gleichzeitig oder auch erst nach einiger Zeit 25 Teile Schwefel zugesetzt . . werden. Die Masse wird darauf 2 Stunden auf 160 bis 165 ° erhitzt. Man erhält ein vorzügliches hartgummiähnliches Produkt. Verwendet man statt 25 Teile nur 10 Teile Schwefel, so erhält man ebenfalls ein gutes Produkt.100 parts of Kondakov's product are mixed with 0 J75 parts of piperidine on a roller, while at the same time or only after some time 25 parts of sulfur were added . . will. The mass is then heated to 160 to 165 ° for 2 hours. You get an excellent hard rubber-like product. If you only use 10 parts instead of 25 parts Sulfur, this is also a good product.
Das neue Produkt zeigt, zumal nach der Politur, einen schönen Schildpatteffekt.The new product shows a nice tortoiseshell effect, especially after polishing.
Selbstredend kann man mit gleichem Erfolg auch direkt das nach Patent 256413 bei Gegenwart von Piperidin gewonnene Polymerisat des ß-y-Dimethylbutadiens verwenden.Of course, you can also use the patent 256413 directly with the same success Use ß-γ-dimethylbutadiene polymer obtained in the presence of piperidine.
