Mixing layered material with one or more plastic additives selected from the group consisting of UV absorbers, hindered amine light stabilizers, antioxidants, colorants, flame retardants, antibacterial agents, and fatty acid additives The mixture is then melt extruded to prepare a pre-exfoliated, natural or synthetic, modified or unmodified layered material. The layered material is, for example, a modified or unmodified layered silicate clay. The layer of layered material in the mixture is expanded to a level below complete delamination. Melt extrusion blends of layered materials and additives are very useful for the preparation of polymer nanocomposites. |
