Poly(acrylic acid) [poly(polypropenoic acid)] (PAA) can form stable and insoluble, colorless hydrogels with HfCl 4 , TiCl 4 , and ZrCl, in water. Two carboxylic groups of PAA are complexed by the M(OH) 2 2+ ions. Hydrogels formed from PAA–MCl 2 ,(OH) 2 , (where M = Hf, Zr) (2 : 1) have found practical application in the blocking of microscopic channels in tooth dentin, and thereby decrease the fluid permeability and protect against tooth decay. © 1996 John Wiley & Sons, Inc.
