Description

Verfahren zur Herstellung von künstlichenGebilden aus Polyvinylchlorid oder Mischpolymerisaten des Vinylchlorids Es ist bekannt, Polyvinylchlorid in Tetrahydrofuran zu lösen und diese Lösung zu verspinnen. J@edo@ch ist dda;s Lö,siun@gsvermögon von Tetrahydrofurani für Hochpolymere dieser Art zur Weiterverarbeitung , insbesondere zum Verspinnen, nicht ausreichend wegen der gallertartigen Beschaffenheit ,der Lösungen.Process for the manufacture of artificial structures from polyvinyl chloride or copolymers of vinyl chloride It is known to use polyvinyl chloride in tetrahydrofuran to solve and spin this solution. J @ edo @ ch is dda; s Lö, siun @ gs Vermögensgon of Tetrahydrofurani for high polymers of this type for further processing, in particular for spinning, not sufficient because of the gelatinous nature of the solutions.

Man hat versucht, diesem Übelstand dadurch zu begegnen, daß man das Polyvinylchlorid vor dem Auflösen ieiner zusätzlichen Chlorierunig unterzog. Dadurch erreicht man zwar eine gesteigerte Löslichkeit, z. B. sogar in. AGetan, aber ein solches Vorgehen bedeutet eine schwere Belastung des Verfahrens diurcheinen zusätzlichen Arbeitsgang.Attempts have been made to counter this evil by doing the Polyvinyl chloride subjected to additional chlorination before dissolving. Through this although one achieves an increased solubility, z. B. even in. AGetan, but a such an approach imposes a heavy burden on the process by an additional one Operation.

Auch wenn man die Verspinnbarkeit dadurch verbessert, daß man die Lösungen vor dem Verspinnen ,auf z. B. 5o° erwärmt und bei dieser Temperatur arbeitet, kommt man zu keinem befriedigernden Ergebnis. Dabei treten, da man sich in der Nähe des Siedepunktes des Lösungsmittels befindet, leicht Bläischen im Eadien auf, die seine Qualität erheblich herabsetzen. Auch: wird der Faden durch das Spinnen bleierhöhter Temperatur spröder, so daß @ddurch das nachtr4gliche Verstrecken die optimalen Festigkeitswerte nicht mehr erreicht werden können.Even if the spinnability is improved by the Solutions before spinning, on e.g. B. 5o ° heated and works at this temperature, one does not come to a satisfactory result. Thereby step as you are close of the boiling point of the solvent is, slightly Beae in the Eadien to the significantly degrade its quality. Also: the thread becomes higher in lead through spinning The temperature is more brittle, so that the optimum strength values are achieved through the subsequent stretching can no longer be reached.

In der französischen Patentschrift 883 764 ist eine iganze Reihe von Lactonden .angegeben worden, welche sich als Lösungsmittel für hochpolymere Vinylverbinddungen bzw. Mschpolymerisate aus ihnen ;eignen sollen. Derartige Lösungsmittel bzw. KombInationen von solchen ergeben aber bei Polyvinylchlo.rxd keime für die Erzeugung hochwextiger Fäden brauchbaren Spinnlösungen. Das gleiche gilt für die in der französischen Patentsichrift 883 763 aufgeführten Lactame. Zur Erhöhung tder Löslichkeit der Polyvinyl- chlori;de hat man .diesen bei der Folymerisatüon gewiss Mengen anderer Vinylverb'indungen zuge- setzt. Zwar konnte !dadurch die Löslichkeit des P,olyvinylchlorids tatsächlich verbessert werden, man erkaufte ;aber diesen Effekt durch verschlechterte Textildaten,der daraus #ers:p:otinenien Fäden. Es zeigte sich aber, daß man auf ganz einfachem Wege zu ;guten Spi#unlösungen aus Polyvinyl- chlorid gelangen. kann, woraus hochwertige Fäden erspionnen werden können, wenn man Tetrahydro- furan ;als Lösungsmittel gewisse Mengen von Di- methylformamid zusetzt. Diese B,e;obachtumg ist des- haJb überraschend, weil weder Tetrahydrofman noch Dimlethylformamid für sich allein brauchbare Lösungsmittel @darstellen.. Erst durch eingehende Versuche konnte ermittelt werden, in welchem Misichu4gsb@ereich die beiden Lösungsmittel an- gewendet werden könnten. Auf Grund der Versuche ergab sich Bein Effekt bereits bei einer Zugalbe vorn ,etwa. 5% Dimlethylformamid zum Tetrahydro- furau.. Dieser ließ sich steigern durch weiteren Zu- satz von Dimethylformamid. Erst wenn- die Di- methylfo.rmamdkompo,niente des Gemisches stark überwiegt, verblaßt der Effekt. Als ein besonders günstiges Mischungsverhältnis ergab. sich ein solches von einem Teil Dimethylformamid und drei Teilen Tetrahydrofuxjan. Es wurde weiterhin gefunden, daß an Stelle des Dimethylformamids auch andere S,äureamide in gleicher Richtung wirken,. Lösungsmittel dieser Art sind N-Fonnylpyrrolidiui, N-Formylpiperidin, N-Di- methylmethoxya.cet,amid. Derartige- Lösungsmittel sind für Lösungen von Polyacrylnitrilen schon vorgeschlagen worden. Sie @eignen sich allein je- doch nicht für die Herstellung von Piolyvinyl- chloridspimp lö.sungen. Nur wentn man sie im Sinn der Erfindung in den oben angeführten Mengen Tetrahydrofuran zusetzt, kann man zu den hier er- strebten hochwertigen Spinnlösungen gelangen. Mann kann auch so vorgehen, daß man- dem Tetra- hydrüfuran mehrere der @obenerwähnten Lösun:gs- mittelkomponenten zusetzt, wobei man von jeder einzelnen entsprechend weniger verwendet. Das Verfahren eignet sich auch für Mischpoly- merisabe !dies Vinylchlorids,. Einer ;der wesentlIchsten-Vorteile der Verwendung von Spinnl@ösungem nasch .der Erfindung ist der Um- stand, daß diese bei Zimmertemperatur versponnen werden können, und zwar sowohl mach Naß- wie nach Trockenspinüverfahren,, Es resultieren Fäden mit Festqgketem vorn 2,5 bis 3 g/den und Dehnungen von i 5 bis 25%#. Bei@sp-iiele 1.. 250 g P@olyviiiylchlo-riid werden in eine Mischung von i5og Dimethylformamid und 6oog Tetrahydro@uran bei 2o° hinter Rühren- -eingetragen, die Mischung bunter Rühren bis zum Sieden ;er- wärmt und, wenn völlige Lösung @eüngetreten ist, auf 20° albgekühlt. Man verspinnt in üblicher Weise in Wasser, jund nvar bei 20°. 2. i 2o g Polyvinylchlorid werden in eine Mischung von 8o g N-Förmylpyrrolsdin und 400,-, Tetrahydrofuran bei 2o° eingetragen, die Mischung im Laufe von 3o Minuten zum Sieden erwärmt und wieder abgekühlt. In the French patent specification 883 764, a whole series of lactones has been indicated, which are said to be suitable as solvents for high-polymer vinyl compounds or polymerizates made from them. In the case of polyvinyl chloride, however, such solvents or combinations of such result in spinning solutions which can be used for the production of highly waxy threads. The same applies to the lactams listed in French patent specification 883,763. To increase the solubility of the polyvinyl chlori; de one has .this at the Folymerisatüon certain quantities of other vinyl compounds puts. It is true that this could reduce the solubility of the P, olyvinylchlorids can actually be improved, man bought; but this effect worsened Textile data that #ers: p: otinenien threads from it. It turned out, however, that one can work on very simple things Ways to; good spi # solutions made of polyvinyl get chloride. can what high quality threads can be spied on if one uses tetrahydro- furan; as a solvent, certain amounts of di- methylformamide added. This B, e; care is therefore haJb surprising because neither Tetrahydrofman Dimlethylformamide can still be used on its own Solvent @represent .. Only through incoming Tests could be determined in which Misichu4gsb @ enrich the two solvents could be turned. On the basis of the attempts there was already a leg effect with a pulling alb in front, about. 5% dimethylformamide to the tetrahydro- furau .. This could be increased by further set of dimethylformamide. Only when- the di- methylfo.rmamdkompo, niente of the mixture strong predominates, the effect pales. As a special one favorable mixing ratio resulted. such a of one part of dimethylformamide and three parts Tetrahydrofuxjan. It was also found that in place of the dimethylformamide also other S, acid amides in act in the same direction. Solvents of this type are N-Fonnylpyrrolidiui, N-Formylpiperidin, N-Di- methylmethoxya.cet, amide. Such solvents are already for solutions of polyacrylonitriles has been proposed. You @ suit yourself alone but not for the production of polyvinyl chloride spimp solutions. You just kept them in mind of the invention in the amounts set out above Tetrahydrofuran, you can add to the here strived to achieve high quality spinning solutions. One can also proceed in such a way that one- the tetra- hydrüfuran several of the @ above-mentioned solutions: gs- middle components added, whereby one of each each less used accordingly. The process is also suitable for mixed poly- merisabe! this vinyl chloride ,. One of the main advantages of using it of Spinnl @ ösungem nasch. The invention is the said that this was spun at room temperature can be, both wet and after dry spinning, threads result with fixed front 2.5 to 3 g / den and stretches from i 5 to 25% #. At @ sp-iiele 1 .. 250 g of P @ olyviiiylchlo-riid are put into a Mixture of 150g dimethylformamide and 60g Tetrahydro @ urane at 2o ° with stirring- - entered, stir the mixture until it boils; warms and, when complete solution @ has occurred, cooled to 20 °.
