    Il     :.Procédé   d'obtention de solutions et depâtes en polymères synthétiques linéaires ". 



   Les polymères synthétiques linéaires   ocmportant   des groupes amides dans leur chaîne, telles que les polyamides ou polyuréthanes,sont en général insolubles dans la plupart des solvants organiques. Seules font exception à cette règle les polyamides mixtes qui sont composées de plusieurs ,constituants aptes à former des polyamides et les polyamides comportant des chaînes latérales aliphatiques.

   Pour ces polyamides et polyuréthanes, on-a déjà proposé toute une série de solvants, dont les plus utilisables sont les alcools aliphatiques inférieurs, mélangés de préférence à de l'eau   et/ou   à des hydrocarbures chlorés, nais, pour les polyamides pures, on a recommandé jusqu'ici presque exclusivement les solvants acides ou phénoliques, tels que l'acide sulfurique, l'acide chlorhydrique, l'acide formique, le   m-orésol   et autres solvants analogues. 



   On a maintenant trouvé que même les polyamides simples insolubles dans l'alcool se dissolvent facilement et peuvent être plastifiées lorsqu'on utilise comme solvants ou plastifiants des composés organiques amino ou oxy contenant du soufre. 



  'aptitude de ces solutions à être diluées est très satisfaisante, On peut ajouter des quantités relativement grandes de diluants non solvants tels que l'eau. On peut aussi envisager   l'uti-   lisation d'autres solvants ou diluants organiques, tels que des   .alcools   et hydrocarbures chlorés, et on obtient avec eux des solutions bien stables.   Comme.exemples   de composés amino ou de composés oxy contenant du soufre, on peut citer :

   les thioéthers contenant des groupes hydroxyle ou des groupes amino, tels que le dioxydiéthylesulfure, le dioxydipropylesulfure, le diaminodiéthylesulfure, le   diaminodiprqpylesul-   fure, ou encore les thiourées et leurs dérivés, les   aminothia-   zols, tels que le 2-aminothiazol, le 2-amino-4-méthyle-thiazol et beaucoup   d'autres,  
Les solutions préparées conformément   à' l'invention   sont utilisées de façon connue pour la fabrication de corps conformés tels que filaments et feuilles, mais aussi pour la   produc-   tion de revêtements, laques et produits similaires. 



   Voici quelques exemples de réalisation du procédé objet de l'invention.

    It: .Process for obtaining solutions and pastes made of linear synthetic polymers.



   Linear synthetic polymers carrying amide groups in their chain, such as polyamides or polyurethanes, are generally insoluble in most organic solvents. The only exceptions to this rule are mixed polyamides which are composed of several constituents capable of forming polyamides and polyamides comprising aliphatic side chains.

   For these polyamides and polyurethanes, a whole series of solvents has already been proposed, the most useful of which are lower aliphatic alcohols, preferably mixed with water and / or with chlorinated hydrocarbons, but, for pure polyamides, Acidic or phenolic solvents, such as sulfuric acid, hydrochloric acid, formic acid, m-oreol and other similar solvents, have heretofore been almost exclusively recommended.



   It has now been found that even simple alcohol-insoluble polyamides dissolve easily and can be plasticized when organic amino or oxy-containing sulfur compounds are used as solvents or plasticizers.



  The ability of these solutions to be diluted is very good. Relatively large amounts of non-solvent diluents such as water can be added. It is also possible to envisage the use of other organic solvents or diluents, such as alcohols and chlorinated hydrocarbons, and very stable solutions are obtained with them. As examples of amino compounds or oxy compounds containing sulfur, there may be mentioned:

   thioethers containing hydroxyl groups or amino groups, such as dioxydiethylesulphide, dioxydipropylesulphide, diaminodiethylesulphide, diaminodiprqpylesul- fure, or thioureas and their derivatives, aminothiazols, such as 2-aminothiazol, 2- amino-4-methyl-thiazol and many others,
The solutions prepared in accordance with the invention are used in known manner for the manufacture of shaped bodies such as filaments and sheets, but also for the production of coatings, lacquers and the like.



   Here are some embodiments of the method which is the subject of the invention.
