    摘要: A macroporous core-shell resin bead having carboxylic acid groups; the bead has from 3% to 100% of monomer residues derived from crosslinker, an average pore diameter of at least 1.5 nm, and an average particle size from 10 μm to 900 μm; wherein at least 90% of the carboxylic acid groups in the bead are in the shell region, and the shell region comprises from 5% to 75% of the bead by volume.
