Description

  

  Verfahren zur Herstellung eines elastischen     kautschukartigen        Körpers.       Im Hauptpatent ist ein Verfahren be  schrieben, gemäss welchem man zu einem  elastischen, kautschukartigen Körper gelangt,  der sich zum Beispiel auch auf den in der       Cxummi-Industrie    gebräuchlichen Maschinen  wie natürlicher Kautschuk verarbeiten, sowie       reit    Füllstoffen, z.

   B.     Zinkoxyd,    Russ, Mag  nesia usw., sowie mit natürlichem Kautschuk,       Faktis,        Regeneraten    usw. mischen, formen  und vulkanisieren lässt, wenn man Schwefel  oder schwefelabgebende Stoffe auf     Äthylen-          dichlorid    in     Gegenwart    eines wässerigen, al  kalischer), alkoholischen oder andern Lösungs  mittels zur- Einwirkung bringt.  



  Es wurde nun gefunden, dass man zu       eiuern    ähnlichen Körper gelangt, wenn man  in     jenem    Verfahren - statt     Äthylendi-          chlorid    - ein Gemisch von     Formaldehyd     und     Äthylendichlorid    verwendet, auf das  man Schwefel oder schwefelabgebende Sub  stanzen in     Polysulfidform,    in der Wärme oder  bei gewöhnlicher Temperatur, einwirken lässt.  Das erhaltene Produkt ist ein     kautschuk.       artiger, elastischer, in Schwefelkohlenstoff  löslicher Körper.  



  <I>Beispiel:</I>  Auf 100 Teile einer wässerigen, alkoholi  schen oder alkalischen Lösung, welche Schwe  fel enthält und zum Beispiel als Lösung von       Schwefelealcium    in     Polysulfidform    dadurch  erhalten wird, dass man     Kalli:hydrat    mit  Schwefel und Wasser kocht und die Lösung  filtriert, wird ein Gemisch von 3 Teilen For  maldehyd und 3 Teilen     Äthylendichlorid     unter Erwärmen zur Einwirkung gebracht.  Es entsteht ein kautschukartiger, elastischer  Körper, der in Schwefelkohlenstoff löslich ist.  Die     Modifikation    des angewandten Schwefels  wird bestimmend für den Grad der Löslich  keit des gebildeten kautschukartigen Körpers  in Schwefelkohlenstoff.

   Die Umwandlung kann       auch    bei gewöhnlicher Temperatur durch  Stehenlassen während einiger Tage durch  geführt werden.



  Method for producing an elastic rubber-like body. In the main patent, a method is be written, according to which one arrives at an elastic, rubber-like body that can be processed, for example, on the machines commonly used in the Cxummi industry, such as natural rubber, as well as fillers such.

   B. zinc oxide, soot, magnesia, etc., as well as mix, shape and vulcanize with natural rubber, factice, regenerates, etc., if you have sulfur or sulfur-releasing substances on ethylene dichloride in the presence of an aqueous, alkaline), alcoholic or other Solution by means of action.



  It has now been found that one arrives at a body similar to egg if one uses in that process - instead of ethylene dichloride - a mixture of formaldehyde and ethylene dichloride, on which one stamps sulfur or sulfur-releasing substances in polysulphide form, in the warmth or at ordinary temperature to act. The product obtained is a rubber. like, elastic body soluble in carbon disulfide.



  <I> Example: </I> For 100 parts of an aqueous, alcoholic or alkaline solution which contains sulfur and which is obtained, for example, as a solution of sulfur-calcium in polysulphide form by boiling calli: hydrate with sulfur and water and the Solution filtered, a mixture of 3 parts of formaldehyde and 3 parts of ethylene dichloride is brought to action with heating. The result is a rubber-like, elastic body that is soluble in carbon disulfide. The modification of the sulfur used is decisive for the degree of solubility of the rubber-like body formed in carbon disulfide.

   The conversion can also be carried out at ordinary temperature by allowing it to stand for a few days.
