Title
(EN) HYDROPHILIC FILTER MEMBRANE WITH PENDANT HYDROPHILIC GROUPS, AND RELATED METHODS OF PREPARATION AND USE
(FR) MEMBRANE DE FILTRE HYDROPHILE AVEC GROUPES HYDROPHILES PENDANTS, ET PROCÉDÉS DE PRÉPARATION ET D'UTILISATION ASSOCIÉS
Abstract
(EN)
Described are hydrophilic polymers (including in the form of a filter membranes that includes hydrophilic polymer) having pendant ionic groups; to methods of making the hydrophilic polymer with pendant ionic groups and derivative membranes and filters; and to method of using the filter membranes for filtering a fluid such as a liquid chemical to remove unwanted material from the fluid.
(FR)
L'invention concerne des polymères hydrophiles (y compris sous la forme d'une membrane de filtre qui comprend un polymère hydrophile) ayant des groupes ioniques pendants ; des procédés de fabrication du polymère hydrophile avec des groupes ioniques pendants et des membranes et des filtres dérivés ; et un procédé d'utilisation des membranes de filtre pour filtrer un fluide tel qu'un produit chimique liquide afin d'éliminer un matériau indésirable du fluide.
