The compatibilized poly ethylene vinyl acetate copolymer (EVA)/high density polyethylene (HDPE) /organomodified montmorillonite (OMMT) blend nanocomposites were prepared in a co-rotating twin-screw extruder followed by injection molding. Montmorillonite clay was modified by octadecylamine and aminopropyltriethoxysilane to make it organophilic. Maleic anhydride grafted high-density polyethylene was used as a Compatibilizer. Nanoclay was added in different proportions to the selected EVA/HDPE blend composition. The concentration of nanoclay was varied from1 to 5 phr in the polymer blend. The resulting nanocomposites were evaluated in terms of their water absorption behavior. Moisture absorption behavior of compatibilized blends is lower than their corresponding blend. On adding the nanoclay the moisture absorption behavior of blend nanocomposites changed at 4 phr nanoclay loading.
