Abstract
Ion exchange materials are prepared by retaining a vinyl monomer solution within the interstices of a fiber structure, such as a woven or non-woven fabric, polymerizing these monomers in the presence of an organic solvent sparingly soluble or totally insoluble in water to form a macroreticular polymer, and functionalizing the macroreticular polymer with an ion exchange functional group.
