Rezumat:

A study of the enzymatic degradation of some montmorillonite-containing nanocomposites of poly(vinyl
alcohol) with starch was based on the determinations of mass loss and the reducing sugars. The
degraded residues have been examined by FT-IR spectroscopy and optical microscopy. It has been
established that the nanoparticles hinder degradation, while the susceptibility to enzymatic degradation
varies in the order: PVA/starch/nanocore> PVA/starch/Bentonite > PVA/starch/Peruvian clay.
