Abstract

L'invention concerne des perles de résine polymère échangeuse d'ions. On prépare des perles dures, réticulés, échangeuses d'ions, par polymérisation par radicaux libres en suspension aqueuse d'un monomère monoéthyléniquement insaturé et d'un monomère polyéthyléniquement insaturé, suivie par la fonctionnalisation du copolymere résultant pour lui conférer des propriétés d'échanges ioniques acide ou basique. Les perles obtenues sont plus résistantes à l'écrasement et supportent au moins 50 cycles alternés de traitements par des acides et des bases sans perdre plus de 15 % des perles parfaites originelles.
