IR and Raman Investigation of Some Poly(acrylic) Acid Gels in Aqueous and Neutralized State

Abstract

The modication of local polymeric conformation of poly(acrylic) acid (PAA), induced by hydration and neutralization with triethanol amine (TEA), was investigated by IR and Raman spectroscopy. The eect of water is the perturbation of hydrogen bonds established between dierent polymeric chains and the modication of the local conformation of the polymer. The neutralization with TEA aects the carboxylic groups and modies the local conformation of the polymer. These modications are correlated with the shift and the modication of the characteristics of IR and Raman spectra.
