Abstract

Cette invention concerne une résine d'acétal de polyvinyle poreuse qui possède un indice de propreté ne dépassant 5 ml/l en termes de COD, une conductivité électrique ne dépassant 5 νS/cm, et une quantité de particules dont la taille ne dépasse pas 2,5 νm de 50.000 par cm3. Lorsqu'elle est utilisée pour le nettoyage d'une chambre propre ou dans d'autres applications, cette résine poreuse permet de réduire ou d'éliminer les pré-traitements qui sont nécessaires en l'état actuel de la technique comme, par exemple, un traitement consistant à effectuer un prélavage suffisant de la résine poreuse afin d'éviter l'élution des impuretés.
