Description
Weichmachungs- und Gelatinierungsmittel Es wurde gefunden, daB Diaryl- oder Aralkylketone der allgemeinen Formel (worin X einen Alkoxy-, Aryloxy-, Alkylthio-, Arylthio- oder Benzylrest, R einen Methyl- oder Phenylrest bedeutet) ausgezeichnete Weichmachungs-und Gelatinierungsmittel für thermoplastische hochmolekulare Verbindungen sind.Softening and gelatinizing agents It has been found that diaryl or aralkyl ketones of the general formula (where X is an alkoxy, aryloxy, alkylthio, arylthio or benzyl radical, and R is a methyl or phenyl radical) are excellent plasticizers and gelatinizers for thermoplastic high molecular weight compounds.
Als Verbindungen der genannten Art seien 4.-Phenoxy-acetophenon, 4-Phenoxy-benzophenon, q.-Athoxyacetophenon, 4-Methoxy-benzophenon, 3-Methoxybenzophenon, 4-Benzyl-acetophenon und 4.-Acetyldiphenylsulfid genannt. Die genannten Verbindungen üben einen guten Weichmachungs- und Gelatinierungseffekt auf die verschiedenartigsten thermoplastischen hochmolekularen Verbindungen, wie beispielsweise Polyvinylchlorid, Polyamide, Polystyrol, Polyvinylacetat, sowie bei Celluloseabkömmlingen insbesondere auf acetylierte Cellulose aus.As compounds of the type mentioned are 4.-phenoxy-acetophenone, 4-phenoxy-benzophenone, q.-Athoxyacetophenone, 4-methoxy-benzophenone, 3-methoxybenzophenone, 4-benzyl-acetophenone and 4.-Acetyldiphenylsulfid called. The mentioned connections practice a good one Softening and gelatinizing effect on a wide variety of thermoplastics high molecular weight compounds such as polyvinyl chloride, polyamides, polystyrene, Polyvinyl acetate and, in the case of cellulose derivatives, especially acetylated cellulose the end.
Es ist überraschend, daB die genannten Verbindungen diese gute Wirkung ausüben, da z. B. Verbindungen wie Diphenylmethan und Diphenylsulfid praktisch ohne Wirkung sind.It is surprising that the compounds mentioned have this good effect exercise, as z. B. Compounds such as diphenylmethane and diphenyl sulfide practically without Effect are.
Beispiel i 7o Teile Celluloseacetat mit 55 °/o gebundener Essigsäure werden in Aceton gelöst und nach dem Verdünnen mit Methanol mit 3o Teilen 4-Phenoxyacetophenonversetzt. NachVerarbeitungderMischung im Kneter und anschließend auf der Walze bei z2o° erhält man eine vollständig homogene Masse, welche ausgezeichnet für den Spritzguß geeignet ist.Example i 70 parts of cellulose acetate with 55% bound acetic acid are dissolved in acetone and after diluting with methanol with 3o parts of 4-phenoxyacetophenone added. After processing the mixture in the kneader and then on the roller at z2o ° a completely homogeneous mass is obtained, which is ideal for injection molding.
Mit gleichem Erfolg kann man an Stelle des genannten Ketons auch 4-Benzyl-acetophenon verwenden.With the same success, 4-benzyl-acetophenone can also be used in place of the ketone mentioned use.
Beispiel 2 65 Teile Polyvinylchlorid werden mit 35 Teilen 4-Äthoxy-benzophenon bei 70° 15 Stunden lang vorgelatiniert. Anschließend wird bei 13o bis r4o° auf einer Mischwalze homogenisiert. Das so erhaltene Walzfell kann zu verschiedenen Formkörpern verarbeitet werden.Example 2 65 parts of polyvinyl chloride are mixed with 35 parts of 4-ethoxy-benzophenone pregelatinized at 70 ° for 15 hours. Then at 13o to r4o ° on a Mixing roller homogenized. The rolled sheet obtained in this way can be made into various shaped bodies are processed.
An Stelle des genannten Ketons kann auch 4-Phenoxybenzophenon verwendet werden.4-Phenoxybenzophenone can also be used in place of the ketone mentioned will.
Beispiel 3 67 Teile Polyvinylchlorid werden in 35o Teilen Tetrahydrofuran gelöst und mit 33 Teilen 4-Acetyldiphenylsulfid versetzt. Die erhaltene klare Lösung wird auf einer Filmgießmaschine zuFilmen verarbeitet. Diese sind klar, besitzen einen weichen Griff und weisen gute Beständigkeit beim Lagern auf.Example 3 67 parts of polyvinyl chloride are dissolved in 35o parts of tetrahydrofuran dissolved and mixed with 33 parts of 4-acetyldiphenyl sulfide. The clear solution obtained is processed into films on a film casting machine. These are clear, own are soft to the touch and have good storage stability.
Beispiel 4 65 Teile einer hochacetylierten Cellulose mit 61 °/o gebundener Essigsäure werden in Chloroform gelöst und mit 35 Teilen 4-Phenoxy-acetophenon versetzt. Die erhaltene Lösung wird auf der Filmgießmaschine verarbeitet. Man erhält einen klaren Film mit ausgezeichneten Eigenschaften.Example 4 65 parts of a highly acetylated cellulose with 61% bonded Acetic acid is dissolved in chloroform and mixed with 35 parts of 4-phenoxy-acetophenone. The solution obtained is processed on the film casting machine. You get one clear film with excellent properties.
