Abstract: Snake-cage resins are described where a phenol is absorbed as a counterion along the cationic sites of a crosslinked threedimensional matrix of a strong base anion-exchange resin initially in the hydroxide form. The absorbed phenol is then polymerized linearly by refluxing in 1:1 mole ratio with formaldehyde in aqueous solution, thus producing a ''''snakecage'''' configuration. Redox polyelectrolytes are derived from polyphenols, and resins capable of binding the monoborate ion from polyphenols or o-hydroxymethyl substituted phenols. The redox capacities of the polyphenolic resins were found to approach theoretical at between 5.1 and 5.4 meq/g. The hydroxymethyl substituted resins are certain of the polyphenolic resins show a marked specificity for absorption of borate ions.
