  Verfahren zur Herstellung von Kautschukmischungen. 



   Bisher fanden die Ester der Adipinsäure Verwendung als Weichmachungsmittel bzw. Quellungsmittel für Zelluloid   (britische   Patentschrift Nr. 22662 A. D. 1901). Es hat sich nun ergeben, dass die   Ester der Adipinsäure und ihrer Abkömmlinge, wie Adipinsäure-methyl-cyelohexyl-ester (Siedepunkt 226-232  C), Methyl-adipinsäure-methyl-eyclohexyl-ester (Siedepunkt 216-224  C), Methyladipin-   säure-isopropylester usw., vorzügliche Kautsehukplastikatoren darstellen. Die Mischungen damit vulkanisieren gut aus und geben nach der Vulkanisation gute, harte Vulkanisate.

   Solche mit den genannten Estern plastizierte Mischungen nehmen in ganz kurzer Zeit   Kautschukfiillmittel   in grossen Mengen leicht auf, insbesondere den sonst so schwer einmischbaren, amerikanischen Gasruss, weshalb sie sich besonders für Reifenmischungen eignen.   Gummisehwammischungen   und   Schaumgummimischungen   werden durch Zusatz der erwähnten Ester so weich, dass leichteste Porenbildung bei der Vulkanisation stattfindet. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of rubber compounds.



   So far, the esters of adipic acid have been used as plasticizers or swelling agents for celluloid (British patent specification No. 22662 A. D. 1901). It has now been found that the esters of adipic acid and its derivatives, such as adipic acid methyl cyelohexyl ester (boiling point 226-232 C), methyl adipic acid methyl eyclohexyl ester (boiling point 216-224 C), methyl adipine isopropyl acid ester, etc., are excellent chewing plasticizers. The mixtures with it vulcanize well and after vulcanization give good, hard vulcanizates.

   Mixtures of this kind plasticized with the esters mentioned take up large amounts of rubber filler in a very short time, in particular American gas black, which is otherwise difficult to mix in, which is why they are particularly suitable for tire compounds. Sponge rubber mixtures and foam rubber mixtures are made so soft by the addition of the esters mentioned that the slightest pore formation takes place during vulcanization.
