Verfahren zur Darstellung eines als Kautschukersatzmittel brauchbaren Produkts.Process for preparing a product useful as a rubber substitute.

Zusatz zum Patent 250920.Addition to patent 250920.

Patentiert im Deutschen Reiche vom 26. Mai 1912 ab. Längste Dauer: 7. August 1926.Patented in the German Empire on May 26, 1912. Longest duration: August 7, 1926.

Durch Patent 250920 ist ein Verfahren zur Darstellung einer dem Kautschuk nahestehenden Substanz geschützt, das darin besteht, daß man das von Kondakow im Journal für praktische Chemie Bd. 64, S. 109/110, beschriebene Produkt mit basischen Agenzien behandelt.Through patent 250920 is a method of making one related to rubber Substance protected, which consists in the fact that Kondakov's in the Journal for practical chemistry vol. 64, p. 109/110, described product treated with basic agents.

Es wurde nun gefunden, daß durch Zusatz von natürlichem Kautschuk zu dem Kondakowschen Produkt ebenfalls ein brauchbarer Kautschukersatz hergestellt werden kann. Das sonst krümelige und sehr schnell verharzende Material wird durch Mischen mit geringen Mengen dieses Körpers haltbar und technisch brauchbar. Vor der Behandlung mit basischen Agenzien hat das Verfahren den Vorzug der Verwendung einer nicht giftigen Substanz.It has now been found that by adding natural rubber to the Kondakov Product can also be used as a substitute for rubber. The otherwise crumbly and resinified very quickly Material becomes durable and technical by mixing with small amounts of this body useful. Before treatment with basic agents, the method has the advantage of Use of a non-toxic substance.

Beispiel.Example.

ioo Teile Kondakowsches Produkt werden allmählich in 5 Teile Para-Kautschuk, der zu einem Fell ausgezogen ist, eingewalzt. Es entsteht ein gut haltbares Kautschukersatzmittel. 100 parts of Kondakov's product gradually turns into 5 parts of para-rubber, which is too a hide is pulled out, rolled in. The result is a durable rubber substitute.
