A sorbitol‐containing resinous polymer has been prepared starting from crosslinked polystyrene–10% divinylbenzene (DVB) resin beads (720–840 μm) by the following series of reactions: (1) chlorosulfonation, (2) sulfonamidation with N ‐propylamine, (3) condensation of sulfonamide with epichlorohydrin, and (4) modification with sorbitol. The resulting sorbitol‐modified polymer has been demonstrated to be an efficient and regenerable specific sorbent for removal of boron in parts per million (ppm) levels. Kinetics of boron sorption and regeneration of the polymer were investigated. © 1998 John Wiley & Sons, Inc. J Appl Polym Sci 68: 2113–2119, 1998
