Abstract
Improved, inert separator beads for separating cation exchange resins from anion exchange resins during regeneration of mixed-bed exchange resins have been discovered. These beads are crosslinked copolymers of methyl methacrylate, styrene and a hydrophilic monomer containing an amide functionality, and have little tendency to clump together or clump at an air-water interface.
