Abstract
Process for preparing cation exchange resin having macroreticular structure, high surface area and lowered apparent density from a macroreticulated copolymer produced by copolymerizing a mixture of a monoethylenically unsaturated monomer and a polyethylenically unsaturated monomer dissolved in an organic liquid which is a solvent for said monomers but unable to substantially swell the resulting copolymer, and macroreticulated cation exchange resin beads produced by the process.
