Description

Verfahren zur Herstellung plastischer lassen. Es wurde gefunden, daß sich die Ester aus Aryloxyessigsäuren bzw. ihren halogensubstituierten Abkömmlingen und Cyclohexanol bzw. seinen Homologen in hervorragender Weise als Zusatzmittel bei der Verarbeitung der Cellulosederivate auf plastische Massen eignen. Es lassen sich z. B. beim Mischen von Nitrocellulose mit verschiedenen Mengen der angeführten Ester Produkte von celluloidartigem Charakter bis zu den weichsten und geschmeidigsten für die Kunstlederfabrikätion geeigneten Filme herstellen.Method of making plastic leave. It was found that the esters of aryloxyacetic acids or their halogen-substituted derivatives and cyclohexanol or its homologues are excellent as additives when processing cellulose derivatives on plastic masses. Leave it z. B. when mixing nitrocellulose with different amounts of the listed Ester products from celluloid-like character to the softest and most pliable Produce films suitable for artificial leather production.

Die neuen 'Ester lassen sich in einfacher Weise durch Erhitzen von Aryloxyessigsäuren bzw. ihren halogensubstituierten Abkömmlingen mit Cyclohexanol bzw. seinen Homologen in Gegenwart geringer Mengen von Säuren darstellen.The new 'esters can be in a simple manner by heating Aryloxyacetic acids or their halogen-substituted derivatives with cyclohexanol or represent its homologues in the presence of small amounts of acids.

Es ist schon vorgeschlagen worden, die Aryloxyessigsäuren bzw. ihre Ester als Zusätze bei .der Celluloidherstellung zu verwenden (vgl. Patentschrift zig636). Diese Produkte sind jedoch deshalb ungeeignet, weil einerseits die Aryloxyessigsäuren selbst und ihre höheren Ester, wie z. B. Phenoxyessigsäurephenylester, nur geringe Gelatinierfähigkeit für Nitracellulose besitzen und außerdem in Lösungsmitteln, wie Sprit, nur wenig löslich sind, anderseits die niederen Ester, wie Phenoxyessigsäuremethyl- und -äthylester, die in Sprit gut löslich sind und Nitrocellulose gut gelatinieren, infolge ihrer niederen Siedepunkte zu flüchtig sind, so daß damit hergestellte Filme bald brüchig werden.It has already been proposed that aryloxyacetic acids or their To use esters as additives in celluloid production (see patent specification zig636). However, these products are unsuitable because, on the one hand, the aryloxyacetic acids themselves and their higher esters, e.g. B. Phenoxyessigsäurephenylester, only low Have the ability to gelatinize nitracellulose and also in solvents, like fuel, are only sparingly soluble, on the other hand the lower esters such as phenoxyacetic acid methyl and ethyl esters, which are readily soluble in fuel and which gelatinize nitrocellulose well, due to their low boiling points are too volatile, so that films made with them soon become brittle.

Beispiele. i. 75 Teile Nitrocellulose werden mit 25 Teilen 2 - q. # 6-Trichlorphenoxyessigsäurecyclohexylester in Gegenwart eines geeigneten Lösungsmittels nach der in der Celluloidindustrie üblichen Methode verarbeitet: Man erhält ein farbloses, geruchloses und völlig klares Celluloid.Examples. i. 75 parts of nitrocellulose are mixed with 25 parts of 2 - q. Cyclohexyl # 6-trichlorophenoxyacetate is processed in the presence of a suitable solvent by the method customary in the celluloid industry: a colorless, odorless and completely clear celluloid is obtained.

2. 5o Teile Nitrocellulose werden mit 5o Teilen Phenoxyessigsäurecyclohexylester, wie im Beispiel i angegeben, verarbeitet. Der entstehende Film zeichnet sich durch große Weichheit und Geschmeidigkeit aus.-2.5o parts of nitrocellulose are mixed with 50 parts of phenoxyacetic acid cyclohexyl ester, as indicated in example i, processed. The resulting film is characterized by great softness and suppleness.
