ABSTRACT:
A process for preparing copolymer beads suitable for conversion to ion exchange resins, comprising forming a polymeric matrix containing a plurality of free radicals, and continuously adding to said matrix, under conditions suitable for polymerizing a monomer feed which is imbibed by and polymerized within the matrices. Ion exchange resins prepared from beads made by such process exhibit improved osmotic and mechanical properties.
