The features of stabilization of excess charges in composites based on PP and disperse metal oxides are investigated by using radiothermoluminescent (RTL) method. It is shown, that introduction of fillers of types of BeO and ZrO2 in to PP leads to change of intensity and temperature realization of β1, β, α α1 peaks on RTL curves and this can be used for prediction of electro active, dielectric and physic-mechanical proper- ties of composites of their base.
