<p>An alkyl-containing porous resin with a specific surface area of 50 to 600 m<2>/g, the resin being prepared by polymerizing a monomer mixture of, based on the total weight 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 50% by weight of a vinylbenzyloxyalkane derivative represented by the formula <CHEM> wherein n is an integer of 1 to 18, a process for its preparation and its use. The porous resin of the invention is capable of fully exhibit its modified functions based on the variations of chemical and structural environments on the surface of resin, the functions being modified by introducing alkyl groups having varying chain lengths.</p> |
