摘要：

The baric dependences of conductivity and permittivity were measured for several metal oxide powders in the pressure range up to 6 GPa. Mixtures of high-density polyethylene (HDPE) with metal oxides after plastic deformation under 2 GPa pressure were studied by differential scanning calorimetry. Pressure treatment caused the formation of mixture metastable states characterized by thermograms containing bimodal peaks of HDPE fusion with enthalpies of 200-280 J/g and broad endothermic peaks in the temperature range 20-100degreesC with enthalpies of 100-200 J/g.
