A diethanolamine pendant polystyrene polymer was prepared by the copolymerization of diethanolaminomethyl styrene, styrene, and divinylbenzene. The composition of the polymer resins produced agreed with copolymerization starting ratios. The polymer resins readily immobilized phenylboronic acid in THF and released pure phenylboronic acid quantitatively in THF/water/acetic acid. (C) 2000 Elsevier Science Ltd. All rights reserved.
