Abstract of the Disclosure Hard, infusible, discrete beads of crosslinked copolymer are prepared by free-radical catalyzed poly- merization of a monomer mixture in aqueous dispersion wherein a minor amount of a modifier, specifically an organic compound containing acetylenic or allylic unsaturation having the ability to moderate the rate of polymerization, is incorporated in the monomer mixture. Ion exchange resins having improved mechanical strength are obtained by attaching functional groups to the copolymer.
