ABSTRACT:
Hard, infusible, discrete beads of crosslinked copolymer are prepared by free-radical catalyzed polymerization of a monomer mixture in aqueous dispersion wherein oxygen is incorporated in the monomer mixture. Ion exchange resins having improved mechanical strength are obtained by attaching functional groups to the copolymer.
