    • A functional group-containing porous resin prepared by polymerization of a monomer mixture of, based on 100% by weight of the total amount of the monomers, 15 to 97% by weight of divinylbenzene, 0 to 82% by weight of at least one aromatic monovinyl monomer selected from the group consisting of styrene, methylstyrene and ethylvinylbenzene and 3 to 30% by weight of a vinylbenzyloxyalkyl derivative represented by the formula ##STR1## wherein n is an integer of 2 to 16 and A represents a hydroxyl group or a halogen atom, and a process for preparing the same. The above-mentioned porous resin of the invention can fully exhibit its function due to the marked presence of a functional group on the surface of the resin and/or in the neighborhood thereof.
