The localization of un-functionalized MWCNTs in immiscible blends of PET and LDPE was investigated as a function of blend ratio and for a 20:80 PET:LDPE blend as a function of MWCNT loading up to 5 wt%. Theoretical prediction of wetting coefficients; microscopic examination; electrical conductivity measurements; differential scanning calorimetry (DSC) and oscillatory rheology analysis confirmed the MWCNTs preferentially located to the PET phase. For blends where the blend ratio was varied and the MWCNT content kept constant at 2 wt.%; the onset of phase inversion was detected from the formation of a 'droplet in droplet' morphology for the 40:60 PET:LDPE blend. This blend was semi-conductive (104 Ω cm); but when the LDPE content was increased to 80 wt.%; the MWCNTs were confined to isolated PET droplets; the resistivity of the blend increased by 11 orders of magnitude. Crystallization temperature (Tc) and crystalline content (Xc) of the PET component increased; but Tc and Xc for the LDPE phase was unchanged with MWCNT addition. The melt viscosity of the PET:LDPE blend at low frequencies (ω;
