Poly(acrylic acid) (PAA) can form stable and insoluble gels with FeCl 3 in water or in H 2 O 2 (30 wt %). Two carboxylic groups are complexed by the FeCl 2+ ion. PAA‐FeCl 3 (2 : 1) gels have found practical application in the blocking of microscopic channels in tooth dentin and thereby decrease the fluid permeability and protect against tooth decay. © 1993 John Wiley & Sons, Inc.
