Abstract:
Methods of making macroporous cation exchange resins are described. The macroporous cation exchange resins are in the form of particles such as beads that contain a hydrophilic, crosslinked, (meth)acrylic-type polymeric material. The macroporous cation exchange resins are prepared using an inverse suspension polymerization process in the presence of a water soluble, organic, aliphatic porogen having at least three hydroxy groups.
