Definitions

  • the N-hydroxycarboxymethylamides of acrylic and / or methacrylic acid are only moderately water-soluble, their water-soluble alkali metal or ammonium salts, in particular their sodium and potassium salts, are preferably used for the preparation of aqueous solutions of the polymers B.
  • the polymerization is particularly preferably carried out in aqueous solutions which contain mixtures of free acids and their corresponding alkali metal or ammonium salts and preferably have a pH of 2 to 7, particularly preferably 2 to 4.
  • the effectiveness of the polymers B is not significantly impaired, since they additionally contain water-soluble monomers such as acrylic acid, methacrylic acid or their amides in copolymerized form in amounts of up to 20% of their weight.

Claims (3)

  1. Dispersions aqueuses de résines synthétiques, que l'on peut obtenir par le fait de réunir une dispersion aqueuse de départ d'un polymère A, qui possède une température de transition vitreuse de -50 à +60°C et qui est constitué de monomères monoéthyléniquement insaturés, qui, exception faite de radicaux carboxyle et de leurs dérivés, ne portent pas de groupements polymérisables ou mutuellement condensables supplémentaires et éventuellement de butadiène et une solution aqueuse d'un polymère B, qui est essentiellement constitué de N-hydroxycarboxyméthylamides de l'acide acrylique et/ou de l'acide méthacrylique et/ou de sels solubles dans l'eau de ces N-hydroxycarboxyméthylamides, au début, au cours et/ou après la réalisation de la préparation de la dispersion aqueuse de départ, avec la condition que la proportion de matière solide du polymère B, rapportée à la quantité totale de polymère A et de polymère B, atteigne 0,5 à 10°% en poids.
  2. Procédé de préparation de dispersions aqueuse de résines synthétiques suivant la revendication 1, caractérisé en ce qu'au début, au cours et/ou après la réalisation de la préparation d'une dispersion aqueuse de départ d'un polyamide A, on réunit cette dispersion de départ et une solution aqueuse d'un polymère B avec la condition que la proportion de substance solide du polymère B, rapportée à la quantité totale de polymère A et de polymère B, atteigne 0,5 à 10% en poids.
  3. Utilisation de dispersions aqueuses de résines synthétiques suivant la revendication 1, à titre de liants pour la fabrication de nappes de mats de fibres.
