Abstract

Semi-interpenetrating polymeric networks are described. More specifically, the semi-interpenetrating polymeric networks include at least two polymers that are closely associated. The first polymer is an ionic polymer that is not crosslinked. The second polymer is a cross-linked polymer that can be either another ionic polymer or a non-ionic polymer. Methods of making the semi-interpenetrating polymeric networks, articles containing the semi-interpenetrating polymeric networks, and methods of using the semi-interpenetrating polymeric networks are also described. The semi-interpenetrating polymeric networks can function as ion exchange resins.
