Abstract

An investigation involving acrylic acid-based polyelectrolytes has been undertaken in an effort to elucidate structure-property relations in dental materials such as zinc polycarboxylates and glass ionomers. The experimental work involves Fourier Transform Infrared Spectroscopy (FTIR) of poly(acrylic acid) (PAA) aqueous solutions using attenuated reflection. The amount of polymeric material adsorbed on the ionic surfaces was found to decrease with PAA concentration and degree of ionization in the original solution. The number of segments ionically bound to the surface, however, appears to increase with both concentration and degree of ionization as well. The kinetics in setting systems was analyzed by FTIR using actual dental cements and restoratives, and found to vary over a considerable range.
