Functionalization of polymer‐supported pentaerythritol as a general synthesis for the preparation of ion‐binding polymers

Abstract

AbstractPentaerythritol bonded to cross‐linked poly(vinylbenzyl chloride) beads (PE) provides a scaffold onto which ligands can be attached by reaction with reactive compounds such as phosphoryl halides. To broaden the applicability of PE for the preparation of ion‐selective polymers, conditions are reported for the conversion of the hydroxyl group to the bromide, which acts as a better leaving group. The CH2Br moiety thus provides a handle on which an array of ligands can be bound through nucleophilic substitution. In this first in a series of reports, immobilization of diethylamine onto the PE and the ion‐binding affinities of the resulting polymer are described. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.
