| titleOfInvention | Process for preparing aqueous dispersions of magnetic polymer particles with sharp grain size distribution |
| abstract | a) on ajuste la quantité d'eau de la dispersion aqueuse de distribution étalée de manière à ce que la teneur pondérale en particules de polymère magnétisable soit comprise entre environ 1 et 40 % de ladite dispersion ; b) on augmente la concentration en agent tensio-actif de la dispersion obtenue à l'étape a) jusqu'à obtenir deux phases, une phase dite liquide et une phase dite solide ; c) on sépare les deux phases ; d) on recommence éventuellement les étapes a), b) et c) sur la phase solide autant de fois qu'il est nécessaire ; e) on récupère la dispersion aqueuse de distribution resserrée. Process for the preparation of aqueous dispersions of particles of magnetizable polymer of tight distribution from aqueous dispersions of spread distribution, characterized in that: a) the amount of water in the spread aqueous distribution dispersion is adjusted so that the weight content of particles of magnetizable polymer is between approximately 1 and 40% of said dispersion; b) the concentration of surfactant in the dispersion obtained in step a) is increased until two phases are obtained, a so-called liquid phase and a so-called solid phase; c) the two phases are separated; d) steps a), b) and c) are optionally repeated on the solid phase as many times as necessary; e) recovering the tightly dispersed aqueous dispersion. |
