Abstract

Agent sulfonant perfectionné et son utilisation dans la préparation de résines échangeuses d'ions. L'agent sulfonant selon l'invention consiste en une solution d'anhydride sulfurique dans un solvant organique capable de gonfler les polymères par addition, réticulés, de monomères à insaturation éthylénique. Il permet de sulfoner les polymères à des températures plus basses que dans les procédés de la technique antérieure et avec des excès beaucoup moins forts de réactif de sulfonation. L'invention facilite la préparation des résines échangeuses d'ions dont les utilisations sont bien connues.
