HYDROPHILIC FILTER MEMBRANE WITH PENDANT HYDROPHILIC GROUPS, AND RELATED METHODS OF PREPARATION AND USE

Abstract:

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.
