Description

Gelatinierungs- und Weichmachungsmittel Bekanntlich kennt man nur wenige Stoffe, die neben einem guten Gelatinierungs- und Weichhaltungsvermögen für Celluloseester mehrere der gleichzeitig erstrebten Nebeneigenschaften, wie Farblosigkeit, Geruchlosigkeit, Luft- und Lichtbeständigkeit usw., in sich vereinen. Besonders gering ist die Auswahl der für primäre Celluloseacetate, die sogenannten Cellulosetriacetate, in Betracht kommenden Gelatinierungs- und Weichinachungsmittel.Gelatinizing and softening agents As is well known, one only knows few substances that, in addition to good gelatinization and soft retention properties, for Cellulose ester several of the secondary properties sought at the same time, such as colorlessness, Combine odorlessness, resistance to air and light, etc. Particularly There is little choice of primary cellulose acetates, the so-called cellulose triacetates, suitable gelatinizing and softening agents.

Es wurden nun in den Oxydiphenylmethanen, dem 2-Oxy- und dem 4-Oxydiphenylmethan, Stoffe gefunden, die nicht nur ein ausgezeichnetes Gelatinierungsvermögen für die sogenannten Cellulosetriacetate besitzen, sondern auch farblos, geruchlos, luftbeständig und lichtbeständig sind und dabei Eisen nicht angreifen. Die genannten Verbindungen können gemäß Annalen der Chemie Bd.442, S.:238, und Bd. 334, S. 373, hergestellt werden. Sie werden zweckmäßig in gereinigter Form verwandt, weil die ihnen eigentümliche Lichtbeständigkeit durch Anwesenheit von Verunreinigungen beeinträchtigt wird. Analoge Eigenschaften wie die Oxydiphenylmethane zeigen auch ihre in bezug auf den die Hydroxylgruppe tragenden Benzolkern höheren Homologen wie die Phenylkresylmethane. Phenole, die an sich schon zur Verwendung als Kampferersatzmittel für Acetylcellulose vorgeschlagen wurden, sind wegen ihrer leichten Zersetzbarkeit, ihrer geringen Luft-und Lichtbeständigkeit und wegen ihres Geruchs für die Industrie der plastischen Massen äußerst ungeeignet. Da die Oxydiphenylmethane ihrerseits auch phenolische Hydroxylgruppen tragen, rnuß ihre große Beständigkeit neben ihren vorzüglichen gelatinierenden Eigenschaften in besonderem Maße überraschen.There were now in the oxydiphenylmethanes, the 2-oxy- and the 4-oxydiphenylmethane, Substances found that not only have excellent gelatinizing properties for the have so-called cellulose triacetates, but also colorless, odorless, air-resistant and are lightfast and do not attack iron. The mentioned connections can according to Annalen der Chemie Vol. 442, pp. 238, and Vol. 334, p. 373, produced will. They are expediently used in a purified form because they are peculiar to them Resistance to light is impaired by the presence of impurities. Analog Properties like the oxydiphenylmethanes also show their properties in relation to the hydroxyl group bearing benzene nucleus have higher homologues such as the phenylcresylmethane. Phenols that already proposed for use as a camphor substitute for acetyl cellulose are because of their easy decomposability and their poor resistance to air and light and extremely unsuitable for the plastic mass industry because of their odor. Since the oxydiphenylmethanes themselves also carry phenolic hydroxyl groups, so must their great durability in addition to their excellent gelatinizing properties surprise in particular.

Beispiel ioo Teile sogenanntes Cellulosetriacetat werden mit 5oo Teilen eines geeigneten Lösungsmittels, wie z. B. Methylenchlorid, und 5o Teilen 2- oder 4-Oxydiphenylmethan oder ihrem Gemisch in der aus der Fabrikation plastischer Massen bekannten Weise auf Kunststoffe, Filme usw. verarbeitet.Example 100 parts of so-called cellulose triacetate are mixed with 500 parts a suitable solvent, such as. B. methylene chloride, and 5o parts 2- or 4-Oxydiphenylmethane or its mixture in the manufacture of plastic bodies known way processed on plastics, films, etc.
