Abstract

As we have stated in our previous article, ethylene-octene copolymers are much more branched than high density polyethylene, therefore, they have lower crystallinity and melting point and better processability. In addition, due to the enhancement of the desired physical and mechanical properties of the nanocomposites such as higher thermal stability and tensile properties and lower peamability in comparison with that of the pristine polymer, there is a great tendency in using this calss of materials. The improvement in physical and mechanical properties of the nanoconmposites is mainly origined from the large aspect ratios of the organoclay platelets and the interaction between the nano-sized filler and polymers which can also make the transfer of load from the matix to the filler more efficient. Moreover, the variation of viscosity with shear rate and angular frequency can provide invaluable information on the viscoelastic property of polymer melts as well as the processability of nanocomposites. In continuation to our previous paper, our aim in this article is to give some complementary information about the mechanical properties and rheological behaviors of the above-mentioned nanocomposites by reviewing the recently published papers on this area.
