   <EMI ID=1.1> 

  
 <EMI ID=2.1> 

  
Le façonnage de toute une série de polymères supérieurs connus en forme de films, de fibres et d'autres produits constitue un problème technique qui, jusqu'à présent, n'a pas été résolu de façon entièrement satisfaisante, car pour différents de ces composés, les solvants et les plastifiants ne donnent aucun résultat ou bien encore, pour l'une ou l'autre de ces matières artificielles, les solvants connus sont, soit trop chers, soit trop difficiles à régénérer. Dans d'autres cas, les solvants connus jusqu'à présent ont une forte action corrosive ou sont très nuisibles pour la santé ou présentent un

Est digne de mention, en outre, le fait que ces composés ne doivent pas être employés comme solvants à l'état pur, mais, étant donné qu'ils sont miscibles avec le plus grand nombre des solvants organiques connus jusqu'à l'heure actuelle, peuvent être, à tout moment, coupés avec ces solvants.

Ces composés, qui constituent presque tous des corps solides à la température ordinaire, s'incorporent aux matières artificielles qui doivent être ramollies par pétrissage ou laminage suivant des procédés connus en soi avec le secours de la chaleur à raison de quantités allant jusqu'à 50 %, ce qui plastifie les polymères supérieurs et permet de travailler ensuite ceux-ci plus facilement. De même que pour l'emploi des lactones comme solvants, il n'est pas nécessaire non plus, dans ce cas; d*employer des lactones purs, on obtient souvent des effets nouveaux en se servant de mélanges de plastifiants déjà connus avec des lactones.

   On mentionnera encore expressément que l'emploi des laotones n'est nullement limité aux polymères linéaires supérieurs mentionnés à l'origine, mais qu'un grand nombre encore d'autres matières artificielles staccomodent très bien du groupe de solvants et de plastifiants revendiqué par la présente demande de brevet.



   <EMI ID = 1.1>

  
 <EMI ID = 2.1>

  
The shaping of a whole series of known higher polymers into films, fibers and other products is a technical problem which, heretofore, has not been solved entirely satisfactorily, since for different of these compounds , the solvents and the plasticizers do not give any result or else, for one or the other of these artificial materials, the known solvents are either too expensive or too difficult to regenerate. In other cases, the solvents known hitherto have a strong corrosive action or are very harmful to health or present a

We have found that for the entirely different groups of artificial materials which have just been mentioned, extremely effective solvents and plasticizers exist among lactones and preferably oxy acids.

Simple already, butyro-lactone, which has recently become relatively easily accessible from an industrial point of view, possesses an extremely varied dissolving power which makes it possible to prepare without difficulty solutions at high percentages of most of the artificial materials which come. to be cited. However, this dissolving power is not limited to butyro-

Noteworthy, moreover, is the fact that these compounds should not be used as solvents in their pure state, but, since they are miscible with the greatest number of organic solvents known until now. current, can be cut with these solvents at any time.

  
Whereas, until now, the lactones cited by way of example until now had to be considered above all as

propionic and others.

  
These compounds, which almost all constitute solid bodies at room temperature, are incorporated into artificial materials which must be softened by kneading or rolling according to processes known per se with the aid of heat in quantities of up to 50 %, which plasticizes the higher polymers and then allows them to be processed more easily. As for the use of lactones as solvents, it is not necessary either, in this case; With the use of pure lactones, new effects are often obtained by using mixtures of plasticizers already known with lactones.

   It will also be expressly mentioned that the use of laotones is by no means limited to the higher linear polymers originally mentioned, but that a large number of other artificial materials are very well suited to the group of solvents and plasticizers claimed by present patent application.
