Abstract
L'invention a trait au domaine des résines échangeuses d'ions. Elle concerne la production de résines amphotères d'échange ionique régénérables par la chaleur, par en capsulage de particules d'échange ionique d'une polymère d'acide faible dans une matrice d'un polymère de type opposé d'échange ionique en présence de certains agents qui inhibent la formation de sels délétères entre les résines. Application à la déminéralisation de solutions salines.
