  Verfahren zur Herstellung von hochwertigen Gummiartikeln. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
 EMI2.1 
 Lösung des Dekahydroehinaldinsalzes des   Dithioearbamats,   das sich vom Dekahydrochinaldin ableitet, in geeigneter Weise verwalzt und bei 2,5 bis 3 Atm. Dampfdruck vulkanisiert. Man erhält ausgezeichnete Vulkanisate, die eine Zerreissfestigkeit von zirka 270 kg pro Quadratzentimeter bei 500 bis   600%   Dehnung und 45 bis   47%   Elastizität besitzen und die wegen ihrer sehr guten Widerstandsfähigkeit gegen Abreibung selbst für Zwecke stärkster Beanspruchung brauchbar sind. 



   Beispiel 3 : Ein nach Beispiel 2 aus 50 Gewichtsteilen Butadien und 15   Gewichtsteilen, a-Methyl-   styrol hergestelltes Mischpolymerisat zeigt, in derselben Vulkanisationsmischung vulkanisiert, eine Zerreissfestigkeit von 200 bis 230 kg pro Quadratzentimeter Festigkeit bei einer Dehnung von zirka 500 bis   600%   und einer Elastizität von 41 bis   42%.   



   Die zur Verwendung gelangenden Russmengen können in weiten Grenzen schwanken, doch sei erwähnt, dass zirka 20 bis 70% Russ bei den Vulkanisationsmischungen mit Erfolg verwendet werden können. Auch können alle gebräuchlichen, nicht genannten Füllmittel anorganischer oder organischer Natur, Plastizierungsmittel, Vulkanisationsbeschleuniger neben Russ verwendet und ebenfalls die Vulkanisation, ausser mit Schwefel, mit anderen bekannten Mitteln, wie z. B. Selen, aromatischen Nitroverbin-   dnngen   usw., ausgeführt werden.

 EMI2.1
 Solution of the Dekahydroehinaldin salt of Dithioearbamats, which is derived from Dekahydrochinaldin, rolled in a suitable manner and at 2.5 to 3 atm. Vulcanized vapor pressure. Excellent vulcanizates are obtained which have a tensile strength of about 270 kg per square centimeter at 500 to 600% elongation and 45 to 47% elasticity and which, because of their very good resistance to abrasion, can be used even for the most demanding purposes.



   Example 3: A copolymer produced according to Example 2 from 50 parts by weight of butadiene and 15 parts by weight of α-methyl styrene shows, vulcanized in the same vulcanization mixture, a tensile strength of 200 to 230 kg per square centimeter of strength at an elongation of approximately 500 to 600% and one Elasticity from 41 to 42%.



   The amount of carbon black that is used can vary within wide limits, but it should be mentioned that around 20 to 70% carbon black can be used successfully in the vulcanization mixtures. All common, not mentioned fillers of inorganic or organic nature, plasticizers, vulcanization accelerators in addition to carbon black can be used and vulcanization, except with sulfur, with other known agents, such as. B. selenium, aromatic nitro compounds, etc., are carried out.

PATENT-ANSPRUCH : Verfahren zur Herstellung von hochwertigen gummiartigen Produkten aus Mischpolymerisaten, die durch Polymerisation von Butadienkohlenwasserstoffen im Gemisch mit Olefinbenzolen oder Homologen derselben oder durch Weiterpolymerisation von unfertigen Polymerisaten dieser Kohlenwasserstoffe oder von unfertigen Polymerisaten der einen Gruppe mit unpolymerisiertem Kohlenwasserstoff der andern Gruppe erhältlich sind, dadurch gekennzeichnet, dass man diese Mischpolymerisate in Gegenwart von feinverteiltem Kohlenstoff (Russ) vulkanisiert. PATENT CLAIM: Process for the production of high-quality rubber-like products from copolymers which are obtainable by polymerizing butadiene hydrocarbons in a mixture with olefin benzenes or homologues thereof or by further polymerizing unfinished polymers of these hydrocarbons or unfinished polymers of one group with unpolymerized hydrocarbons of the other group, characterized in that these copolymers are vulcanized in the presence of finely divided carbon (soot).
