    The given work presents the experimental data on study of temperature dependences c (T) and angle tangent of dielectric losses tgδ (T) of polypropylene (PP) and composites on the basis of beryllium oxide BeO at different components ratios as well as investigation of radiothermoluminessence (RTL) in these systems. Comparing the results on temperature dependencies of dielectric permittivity s, angle tangent of dielectric lasses tgδ and RTL spectra of the studied compositions one can say that observed low -temperature maximum in temperature dependence of electro physical parameters (Ɛ and tgδ) of composites is the result of change of polymer matrix macromolecules molecular mobility and its effect on interfacial interaction with filler. The electro active polymeric films and compositions on their basis are used as sensitive elements, dosimeters, sensors in many branches of industiy, sensor electronics, ecology, etc.[l] Therefore, the study of their electroactive dielectric, sensor properties as well as establishment of interrelation of these properties with structural peculiarities, preparation technology, filling techniques, polarization the methods are the urgent. [2] It should be noted that many properties of composite materials are determined by interfacial interaction in polymer - filler system and its mechanism understanding will allow modification or prediction of their operating characteristic. [3] The present work object was the determination of interrelation between the dielectric properties and interfacial interaction polymer-filler.
