摘要：
During a study of different treatments of fibers employed to reinforce cements, IR spectra of acrylonitrile-methyl acrilate copolymer in solid state, untreated and treated with different media (distilled water, basic aqueous solutions) have been recorded. These spectra have been analyzed and assigned on the basis of spectral comparison with spectra of analogous ones previously studied. Treated fiber spectra exhibit many bands due to the existence of water molecules in the fiber structure. Hydrolysis and hydration processes have been formulated, which explain satisfactorily the spectral assignment proposed. © 1990.
