Poly(vinyl pyrrolidone) was grafted onto crosslinked polystyrene beads through the 2‐chloroethyl sulfonamide (CSA) groups present in the resin using the atom transfer radical polymerization (ATRP) method. A beaded polymer with a poly(vinyl pyrrolidone) surface shell was prepared in three steps, starting from polystyrene‐divinylbenzene (10% crosslinking) based beads with a particle size of 420–590 μm, according to the synthetic protocol; chlorosulfonation, sulfamidation with 2‐chloroethylamine hydrochloride and grafting reaction of poly(vinyl pyrrolidone). The polymeric resin prepared with the described procedure with 72.66% of grafted poly(vinyl pyrrolidone) has also been demonstrated to be an efficient dye sorbent, able to remove dye from water even at ppm levels. The dye sorption capacity under non‐buffered conditions is around 0.65 g dye/g resin. Copyright © 2006 John Wiley & Sons, Ltd.
