The aim of this work was to study the localization of MWCNTs in the immiscible blend of ethylene 1-octene copolymer (EOC) and cyclic olefin copolymer (COC) 80/20. The samples were prepared by different feeding sequences using melt compounding in an internal mixer. The results of the melt linear viscoelastic analysis, FESEM observations and electrical conductivity measurements showed that the MWNTs localized either in the COC droplets or accumulated in the interface even for the hybrid samples in which MWNTs was initially melt mixed with EOC matrix as a thermodynamically unfavorable phase. The results were found to be in good agreement with the predicted results based on wettability. Interestingly the results of the rheological as well as electrical conductivity showed a percolation thresholds in the same range as those reported for the other hybrid systems in which MWNTs localized in the matrix and formed three dimensional network. This was attributed to the migration of MWNTs from unfavorable EOC phase to the interface and forming a MWNTs interconnected network.
