Abstract

The behavior of the hydrogels obtained from the poly(ethylene oxide) (PEO) and from the polyacrylic acid (Carbopol 940 and 980) under the repeated action of the water was investigated by Raman spectroscopy. The analyze of the spectra shows a reversible action of the water on the polymeric matrix..

Keywords
