The influence of preliminary electro processing on a charging condition, piezoelectric and strength properties of a composition on the basis of polyethylene and piezoceramics PCR5 and PCR8, having romboedric and tetragonal structure, respectively, are investigated. It is shown, that observable increase of electrical and mechanical durability for a composition PE+PCR5, PE+PCR8 processed at various Epr after electrothermopolarization is connected with the ordering of physical structure inter phase boundary layer. It was experimentally established, that the intensity of field at electro processing strongly influences a charging condition (concentration and the energy activation) and results in the change of boundary layer properties and the change of properties of a boundary layer influences the strength and piezoelectric properties of a composition.
