Paper Title:
Polyethylene-Clay Nanocomposites Using Ionomeric Compatibilizer
  Abstract

Nanocomposites made of linear low-density polyethylene (LLDPE) and two different types of clays were obtained and studied by using zinc neutralized carboxylate ionomer as a compatibilizer. Two different clays, natural montmorillonite (Closite Na+) and a chemically modified clay Closite 20A has been used. Nanocomposites were prepared by melt blending in a twin-screw extruder using two mixing methods: two-step mixing and one-step mixing. The relative influence of each compatibilizer was observed from structural analysis by WAXD, and mechanical properties. Experimental results confirms that the film samples with ionomer showed good mechanical performance and that the two step mixing conditions resulted in a better dispersion and intercalation for the nanofillers than one step mixing.
