Abstrakt v dalším jazyce:	A new ternary polymer blend was synthesized and characterized in the presentwork. A series of ternary polymer blends comprising water soluble polypyrrole, polyvinyl alcohol, and poly(4-styrenesulfonic acid) were prepared by solution casting method. The structural, electrical, and thermal properties of prepared ternary blends were investigated. X-ray diffraction studies indicated the semicrystalline nature of the polymer blends and chemically interacted polymer chain were revealed by Fourier transform infrared spectra. The morphological phase transformations were observed from scanning electron microscope and atomic force microscopy images. Thermogravimetric analysis explained the thermal degradation process. The ternary blends also possess excellent mechanical stability observed through force versus extension plot. The dielectric constant value of ternary blends was obtained in the range of 600–800 at low frequency range. The highest conductivity obtained was between 101 to 103 S cm1 for ternary blends at higher frequency range. The overall results explains the charge transportation and relaxation process in the ternary blends due to presence of an electric field. The excellent dielectric constant values of ternary blends will be efficient for various electronics applications
