Annotation	The paper describes structure and electric properties of nanocomposites based on polybutylene terephthalate (PBT) filled by multiwalled carbon nanotubes (MWCNTs). Cyclic butylene terephthalate oligomers with low melt viscosity were used for PBT/MWCNTs nanocomposites synthesis to reach better dispersion of MWCNTs. The dependence of electric conductivity of nanocomposites on processing methods was established as well as electrical percolation threshold for PBT/MWCNTs was determined as 0.22 wt. % of MWCNTs.
