摘要: Abstract Blends of linear low density polyethylene (LLDPE) and ethylene-co-methyl acrylate (EMA) their nanocomposites with two types modified montmorillonite (organoclay) were explored in order to achieve an improved balance between stiffness toughness. The prepared a HAAKE RHEOMIX at three different mixing sequences. compression molded utilized evaluate the morphology properties like mechanical, dynamic mechanical thermal. results reveal that are dependent on blending sequence as well type nanoclay used. addition organoclay slightly increases tensile modulus for all nanocomposites. On other hand, drastic improvement impact strength was observed when located dispersed EMA phase. effects clay concentration also studied. optimum dispersion property found nanocomposite 5 wt% nano clay.
