Description
Celatinierungs- und Weichmachungsmittel Trotz der großen Zahl von Stoffen, die als Gelatinierungs- und Weichmachungsmittel für Acetylcellulose schon in Vorschlag gebracht wurden, kennt man tatsächlich nur wenige, die sich für die Verarbeitung der Acetylcellulose auf Kunstprodukte für die verschiedensten Verwendungszwecke in befriedigender Weise eignen, weil von solchen Stoffen neben ihrem guten Gelatinierungs- und Weichhaltungsvermögen auch andere Eigenschaften, wie Farblosigkeit, Geruchlosigkeit, Beständigkeit gegen Licht und Luft usw., verlangt, werden, einer Vereinigung aller dieser Eigenschaften aber nur eine sehr geringe Menge von Stoffen gerecht wird. Insbesondere besteht ein fühlbarer Mangel an hochwertigen Gelatinierungs- und Weichmachungsmitteln für primäre Celluloseacetate, die sogenannten Cellulosetriacetate.Celatinizing and softening agents Despite the large number of Substances that are used as gelatinizing and softening agents for acetyl cellulose In fact, only a few are known to be in favor of the Processing of acetyl cellulose on synthetic products for various purposes are suitable in a satisfactory way because of such substances in addition to their good gelatinization and softness also have other properties, such as colorlessness, odorlessness, Resistance to light and air, etc., are required, to be a union of all However, only a very small number of substances meet these properties. In particular, there is a noticeable lack of high-quality gelatinizing and softening agents for primary cellulose acetates, the so-called cellulose triacetates.
In der Patentschrift 565 5i9 der Klasse 39b 3 ist inzwischen dargelegt worden, daß gewisse Phenolabkömmlinge besonders geeignete Gelatinierungs- und Weichmachungs-#mittel für Cellulosetriacetate sind. Nunmehr wurde gefunden, daß sich auch Verwandte der dort genannten Oxydiphenylmetbane und ihrer Homologen, nämlich die Oxydiphenyle, für den gleichen Zweck nicht minder gut eignen.In the patent specification 565 5i9 of class 39b 3 is set out in the meantime It has been found that certain phenol derivatives are particularly suitable gelatinizing and softening agents for cellulose triacetates are. It has now been found that relatives of the there mentioned oxydiphenylmetbanes and their homologues, namely the oxydiphenyls, No less suitable for the same purpose.
Die erfindungsgemäß für sich oder im Gemisch als Gelatinierungs- und Weichmachungsmittel in Betracht kommenden Oxydiphenyle tragen nur eine phenolische Hydroxylgruppe, können aber im übrigen an einem der beiden Benzolringe oder an beiden, z. B. durch Alkylgruppen, Aminogruppen u. dgl., auch substituiert sein. Man erhält diese Verbindungen beispielsweise nach den Angaben in Beilsteins Handbuch der organischen Chemie ¢. Auflage, Band 6, Zeile 672 ff. Beispiele i. ioo Teile Cellulosetriacetat werden mit etwa 5o Teilen 2 -Oxydiphenyl unter Zusatz von 5oo Teilen eines geeigneten Lösungsmittels, wie Methylenchlorid, oder eines Lösungsmittelgemischs, wie Methylenchloridalkohol, in der aus der Celluloidindustrie bekannten Weise auf Kunststoffe, wie plastische Massen, Filme, Lacke u. dgl., verarbeitet.According to the invention alone or in a mixture as gelatinizing and Plasticizers eligible oxydiphenyls have only one phenolic Hydroxyl group, but can otherwise be on one of the two benzene rings or on both, z. B. be substituted by alkyl groups, amino groups and the like. You get these compounds, for example, according to the information in Beilstein's Handbook of Organic Chemistry ¢. Edition, Volume 6, Line 672 ff. Examples i. 100 parts cellulose triacetate are with about 5o parts of 2-oxydiphenyl with the addition of 500 parts of a suitable one Solvent, such as methylene chloride, or a mixture of solvents, such as methylene chloride alcohol, in the manner known from the celluloid industry to plastics such as plastic Masses, films, lacquers and the like, processed.
2. ioo Teile Cellulosediacetat werden mit 3o bis 6o Teilen 2-Oxydiphenyl in 5oo bis 7oo Teilen eines geeigneten Lösungsmittels, z. B. Aceton, gelöst. Aus der filtrierten Lösung werden in bekannter Weise, z. B. durch Gießen auf Glasplatten, Filme hergestellt.2. 100 parts of cellulose diacetate are mixed with 3o to 6o parts of 2-oxydiphenyl in 500 to 700 parts of a suitable solvent, e.g. B. acetone, dissolved. the end the filtered solution are in a known manner, for. B. by pouring onto glass plates, Films made.
