AB  - Non-modified Multiwalled Carbon Nanotubes (MWCNT) and polypropylene (PP) in 
      absence of compatibilizer have been chosen to elaborate MWCNT/PP nanocomposites 
      using a simple melt-mixing dispersing method. Calorimetry results indicate little 
      effect of MWCNTs on crystallinity of PP, revealing not much interaction between 
      nanotubes and PP chains, which is compatible with the employed manufacturing 
      procedure. In any case, a hindering of polymer chains motion by MWCNTs is 
      observed in the molten state, using oscillatory flow experiments, and a 
      rheological percolation threshold is determined. The percolation limit is not 
      noticed by Pressure-Volume-Temperature (PVT) measurements in the melt, because 
      this technique rather detects local motions. Keeping the nanocomposites in the 
      molten state provokes an electrical conductivity increase of several orders of 
      magnitude, but on ulterior crystallization, the conductivity decreases, probably 
      due to a reduction of the ionic conductivity. For a concentration of 2% MWCNTs, 
      in the limit of percolation, the conductivity decreases considerably more, 
      because percolation network constituted in the molten state is unstable and is 
      destroyed during crystallization.
