Rezumat

New nanocomposites based on high density polyethylene (HDPE) and organically modifi ed nanoclay (Cloisite 20A) were obtained by two different methods, namely melt compounding and solution blending, and their properties were comparatively studied by XRD, DSC, POM and SEM in order to establish the dependence of the clay degree of exfoliation/intercalation on the preparation procedure. Nanocomposites prepared in molten state under shear stress were found to posses the most extensive dispersion of nanometric clay particles and high levels of exfoliation.
