Description

Verfahren zur Erhöhung derWeichheit und Elastizität von Celluloseester- oder -äthermass Es ist gefunden worden, daß die Verbindungen der Zusammensetzung R-SO-R,. oder R-SO-SO-R., worin R einen Aryl- oder Aralky lrest, Al ebenfalls einen Aryl-, Alkyl-oder ÄralkvIrest bedeutet, sich als Kampferersatz oder Weichhaltungsmittel für die Herstellung plastischer Massen aus Celluloseestern oder _:#tliern, z. B. \ itrocellulose, Acetylcellulose u. dgl. gut eignen. Sie kristallisieren nicht aus und erzeugen zähe Massen. Auch halben sie den Vorteil, sich wässrig mit Nitrocellulose_ verkneten zu lassen. Die Verbindungeji der Zusammensetzung R-SO-R, geben vorzugsweise weiche, die .der Zusammensetzung R-SO-SO-Rl vorzugsweise elastische Massen. Die Darstellung der angegebenen Körper ist bekannt. Für die Zwecke der Praxis kommen insbesondere die Diphenylsulfoxyde oder die Diphenyl- oder Ditolvtdisulfoxvde in Betracht.Process to increase the softness and elasticity of cellulose ester or -äthermass It has been found that the compounds of the composition R-SO-R ,. or R-SO-SO-R., in which R is an aryl or aralky radical, Al is also an Aryl, alkyl or AralkvIrest means themselves as a camphor substitute or softening agent for the production of plastic masses from cellulose esters or _: # tliern, z. B. \ itrocellulose, acetylcellulose and the like are well suited. They don't crystallize out and produce tough masses. They also half the advantage of being watery with nitrocellulose_ to knead. The compounds of the composition R-SO-R are preferably soft, the composition R-SO-SO-Rl preferably elastic masses. the Representation of the specified body is known. Come for practice purposes in particular the diphenyl sulfoxides or the diphenyl or ditol disulfoxides in Consideration.

Als Kampferersatzinittel bei der üblichen Cellulöidherstellung hat man zwar bereits Dioxydiphenylsulfon vorgeschlagen.- Die bei dem vorliegenden Verfahren verwerideteii Sulfoxyde sind jedoch nicht ohne weiteres mit den St@lfonen vergleichbar. Außerdem haben clie nach vorliegendem Verfahren vervendeten Sulfoycle den Sulfonen gegenüber den 'Vor-7.ug, daß sie nicht aus den -ihnen auskristallisieren und die \ itrocellulose viel besser gelatinieren. Das Dioxy diphenylsulfon dagegen als Kainpferersatzmittel nicht eignet, weil es aus den Filmen ausl:rystal siert, wodurch diese brüchig werden. Beispiele. I. 33 Gewichtsteile Ditolvldisulfoxvd w( den mit 66 Gewichtsteilen trockner N iti cellulose in 5oo Raumteilen Essigäther ui 25o Raumteilen Benzol gelöst und nach e folgter Lösung gegossen. a. roo Gewichtsteile \ itrocellulose werd mit 4o Gewichtsteilen Diphenylsulfoxyd, , Gewichtsteilen Aceton und 5o Gewichtsteile Alkohol angefeuchtet und nach erfolgter L sang hei 6o° auf Walzen verknetet. 3. ioo Gewichtsteile Nitrocellulose v< etwa 2o Prozent Wassergehalt werden ni oo Gewichtsteilen Ditolyldistilfoxyd genienl und auf etwa 6o° «-armen Walzen bis zt Fntfernung des Wassers verknetet. Dioxydiphenylsulphone has already been proposed as a camphor substitute in the usual cellulose production. In addition, the sulfones used in the present process have the advantage over the sulfones that they do not crystallize out of them, and the cellulose much better gelatinize. The dioxy diphenyl sulfone on the other hand not as a horse substitute suitable because it is out of the films: rystal sated, which makes them brittle. Examples. I. 33 parts by weight of Ditolvldisulfoxvd w ( the 66 parts by weight dryer N iti cellulose in 500 parts by volume, vinegar ether ui 250 parts by volume of benzene dissolved and after e poured the following solution. a. roo parts by weight \ itrocellulose will with 40 parts by weight of diphenyl sulfoxide, Parts by weight of acetone and 50 parts by weight Alcohol moistened and after L sang hot 60 ° kneaded on rollers. 3. 100 parts by weight of nitrocellulose v < about 20 percent water content is ni oo parts by weight of Ditolyldistilfoxyd genienl and on about 60 ° -arm rollers up to zt Removal of the kneaded water.
