Verfahren zur Darstellung eines dem Hartgummi nahestehenden Produktes.
Durch das Stammpatent Nr. 62129 ist ein Verfahren zur Darstellung eines dem vulkanisierten Kautschuk nahestehenden Produktes geschützt, welches darin besteht. dass man das durch Einwirkung von basischen Agenzien auf das von Kondakow im Journal für praktische Chemie, Band 64, Seite 109/110, beschriebene Polymerisationsprodukt des ss-y-Dimethylbutadiens erhältliche Produkt vulkanisiert.
Es wurde nun gefunden, dass bei Verwendung von Piperidin oder seinen Homologen als basische Agenzien besonders guter Hartgummi entsteht. Bemerkenswert ist hiebei, dass man auch bei den Vulkanisationsverfahren, die sonst zum Weichgummi führen, hier einen

gemischt, während gleichzeitig oder auch erst nach einiger Zeit 25 Teile Schwefel zugesetzt werden. Die Masse wird darauf zwei Studen auf 160 bis 165 erhitzt. Man erhält ein vorzügliches hartgummiähnliches Produkt. Verwendet man statt 25 Teilp nur 10 Teile Schwefel, so erhält man ebenfalls ein gutes Produkt. Das neue Produkt zeigt, zumal nach der Politur, einen schönen Schildpatteffekt.
Selbstredend kann man mit gleichem Erfolg auch direkt das nach Patent Nr. 67691 bei Gegenwart von Piperidin gewonnene Polymerisat des ss-γ-Dimethylbutadiens verwenden.

Process for the preparation of a product similar to hard rubber.
The parent patent No. 62129 protects a process for the preparation of a product which is close to vulcanized rubber and which consists therein. that the polymerization product of ss-γ-dimethylbutadiene described by Kondakow in the Journal for Practical Chemistry, Volume 64, page 109/110, is vulcanized.
It has now been found that when piperidine or its homologues are used as basic agents, particularly good hard rubber is produced. It is noteworthy that one is also involved here with the vulcanization processes that otherwise lead to soft rubber

mixed, while at the same time or after some time 25 parts of sulfur are added. The mass is then heated to between 160 and 165 for two hours. An excellent hard rubber-like product is obtained. If you use only 10 parts of sulfur instead of 25 parts, you also get a good product. The new product shows a nice tortoiseshell effect, especially after polishing.
It goes without saying that the polymer of ss- γ-dimethylbutadiene obtained according to Patent No. 67691 in the presence of piperidine can also be used directly with the same success.
