Abstract: The paper views the results of the study of temperature and frequency dependence of the dielectric parameters in polymer composites based on polyethylene and barium titanate. With the introduction of ferroelectric into the polymer matrix an increase in the dielectric constant and dielectric loss tangent was found.

Keywords: dielectric properties, polymer system, ferroelectric ceramic.
