Abstract Based on the FTIR spectral changes, the miscibility of some nanocomposites based on starch, polyvinyl alcohol and treated multilayered silicate, was qualitatively estimated. The FTIR spectroscopy provide evident gross/small spectral changes as well as appreciable spectral shifts mainly in those spectral range that defines hydroxyl O-H vibrations (3600- 3000 cm -1 ), water absorbtion (1800 - 1500 cm -1 ) , the morphological order degree and the interaction with multilayered silicate and (1192 - 950 cm -1 ). Based on the observed spectral modifications it can be estimate that high miscibility do exist between the components of the studied nanocomposites.
