Electret properties of compositions of a semiconductor with semiconductor fillers TlInSe2 and TlInxCe1-x Se2 in a heterogeneous system polymer-semiconductor have been investigated by the method of electret-thermal analysis. It is shown that small change in the structure of the filler results in significant changes in the spectrum of the thermostimulated depolarization currents. It was found that TlInSe2 and TlInxCe1-x Se2 fillers which have p-type conductivity acts as a structure-forming agent in the polypropylene matrix changing crystallinity and supermolecular structure of both polymer and boundary layer of polymer and the filler.
