The impact of talc on the structure and electret properties of high-pressure polyethylene has been investigated. Adding talc in the polymer matrix leads to an increase in the share of crystalline phase polymer with a simultaneous increase in the average size of crystallites was established by x-ray structure analysis. Thermally stimulated depolarization and isothermal relaxation potential has shown increasing stability electret state of the polymer, which can be explained by the change in the structure of the polymer, the new electrically active defects and decrease in the conductivity of the polymer adding in polymeric matrix of talc.
