Three monomers with different chemical nature were used to modify sodium montmorillonite by different paths.The main scope is to convert clay into an organophilic material compatible with polyolefins. In particular these modified clays were mixed with HDPE by melting process. These polymeric materials were characterized and used for film preparation. Those films served to perform pervaporation experiences with cyclohexane as hydrocarbon. It was noticed that barrier properties were affected by the presence of the different monomers into clay lamellas.
