Description

  

  Procédé pour la préparation d'une matière plastique.    La présente invention a pour objet un  procédé pour la. préparation d'une matière  plastique nouvelle, du type aminoplaste.  



  Ce procédé est caractérisé en ce que l'on  fait réagir de la     vinyl-diaminotriazine    avec  du formol, en milieu légèrement alcalin, puis       poursuit    la condensation en milieu acide.  



  <I>Exemple:</I>  On chauffe au bain-marie pendant 1 heure,  au     pli    8, une mole de     vinyl-diaminotriazine          (obtenue    par exemple par action de     dieyan-          diamide    sur le     maléate    d'éthyle et d'ammo  nium, puis saponification) avec 4 moles de  formol. Lorsque la dissolution est complète,  on ajoute 0,2 mole d'acide chlorhydrique et  chauffe encore pendant 10 minutes. On éva  pore ensuite dans le vide le formol en excès,  puis sèche à l'étuve à 60  C. Le     eondensat    ob  tenu peut être durci par chauffage à 135  C    pendant 3 heures. La matière obtenue est       moulable    à 155  C et thermodurcissable.

   Elle  est insoluble dans l'eau, les alcools, les hy  drocarbures aliphatiques ou aromatiques.  Dans la     pyridine,    elle gonfle légèrement, sans  se dissoudre.



  Process for the preparation of a plastic material. The present invention relates to a method for. preparation of a new plastic material, of the aminoplast type.



  This process is characterized in that the vinyl-diaminotriazine is reacted with formalin, in a slightly alkaline medium, then the condensation continues in an acidic medium.



  <I> Example: </I> One mole of vinyl-diaminotriazine (obtained for example by the action of dieyan-diamide on ethyl ammonium maleate) is heated in a water bath for 1 hour, at fold 8. , then saponification) with 4 moles of formalin. When dissolution is complete, 0.2 mole of hydrochloric acid is added and further heated for 10 minutes. The excess formalin is then eva pore in vacuo, then dried in an oven at 60 ° C. The eondensate obtained can be hardened by heating at 135 ° C. for 3 hours. The material obtained is moldable at 155 C and thermosetting.

   It is insoluble in water, alcohols, aliphatic or aromatic hydrocarbons. In pyridine, it swells slightly, without dissolving.
