 <EMI ID=8.1>

 <EMI ID=9.1> 

  
nols polyvalents, s'est surtout le 'carbonate de glycol cyclique, facilement soluble dans l'eau qui est utilisable avec de bons résultats; car on peut l'obtenir très facilement dans l'indus-

  
 <EMI ID=10.1> 

  
 <EMI ID=11.1> 

  
Ces carbonates cycliques et d'autres encore peuvent être employés séparément ou en mélange avec d'autres solvants.

  
Les carbonates cycliques suivant l'invention sont surtout intéressants pour les polymères supérieurs du nitrile acrylique ou pour les produits.de polymérisation mixtes qui renferment du nitrile acrylique'parce que l'on ne dispose que dans des proportions très limitées de.solvants pour ces matières, on peut toutefois aussi s'en servir avec avantage pour la mise à forme ou la plastification d'autres polymères supérieurs, par exemple des esters' et des éthers cellulosiques ou des mélanges de divers polymères supérieurs éventuellement avec utilisation simultanée d'autres plastifiants, de résines ou décharges .

' ' REVENDICATIONS.

  
1.) Procédé pour la mise à forme des polymères supérieurs, notamment des polymères du nitrile acrylique, caractérisé par

  
 <EMI ID=12.1> 

  
lents ou de phénols polyvalents comme solvants et plastifiants.



   <EMI ID = 1.1>

  
 <EMI ID = 2.1>

  
 <EMI ID = 3.1>

  
in particular polymers, acrylic nitrile, fibers, yarns,

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

  
of ring atoms of a similar kind such as, for example, the group of ring atoms'

  

 <EMI ID = 6.1>


  
such as, by. example, those of succinic anhydride and

  
 <EMI ID = 7.1>

  
with cyclic carbons according to the invention

  

 <EMI ID = 8.1>


  
have, in an open chain, (as they; present themselves, - e.g.

  
 <EMI ID = 9.1>

  
polyvalent nols, especially the cyclic glycol carbonate, easily soluble in water which is usable with good results; because it can be obtained very easily in the industry.

  
 <EMI ID = 10.1>

  
 <EMI ID = 11.1>

  
These and other cyclic carbonates can be used separately or in admixture with other solvents.

  
The cyclic carbonates according to the invention are especially useful for the higher polymers of acrylic nitrile or for mixed polymerization products which contain acrylic nitrile because only very limited amounts of solvents are available for these materials. However, it can also be used with advantage for the shaping or plasticization of other higher polymers, for example cellulose esters and ethers or mixtures of various higher polymers optionally with the simultaneous use of other plasticizers, of resins or landfills.

'' CLAIMS.

  
1.) Process for forming higher polymers, in particular polymers of acrylic nitrile, characterized by

  
 <EMI ID = 12.1>

  
slow or polyvalent phenols as solvents and plasticizers.
