Polypyrrole (PPY ) was electrophilically polycondensed with phthalic anhydride ( P A ) and pyromellitic dianhydride ( PMDA) . PPY-PA and PPY-PMDA polycondensates were evaluated in regard to their thermal stability and dielectric and conductivity behavior. The overall thermal stability is in the orde
