Patent

CA 2588675

Hydrophilic porous polymeric membranes with high permeabilities, and processes for the preparation thereof are disclosed. Membranes may be prepared by including a preferably hydrophilic cross-linkable component such as PVP (either by inclusion into the polymer dope prior to casting, or coating or quenching cast membranes); and treating the polymeric microfiltration or ultrafiltration membrane with a crosslmking agent to cross-link said cross- linkable component. Preferred cross-linking agents include Fenton's reagent.

L~invention décrit des membranes polymères poreuses hydrophiles de perméabilités élevées ainsi que des procédés pour les préparer. Les membranes peuvent être préparées en incluant un composant réticulable de préférence hydrophile tel qu~un PVP (par inclusion dans la masse de polymère avant coulage, ou par enduction ou trempe de membranes coulées) et en traitant la membrane polymère pour micro ou ultrafiltration à l~aide d~un agent de réticulation dont le but est de réticuler ledit composant réticulable. Le réactif de Fenton fait partie des agents de réticulation préférés.
