## Abstract Polypyrrole/poly (vinyl chloride) semi‐interpenetrating networks of different compositions are prepared using ammonium per sulfate initiator at room temperature in pellet form and film form and their dielectric properties are studied at different microwave frequencies. An HP 8510 Vector
Blends were obtained by impregnation of an insulating polymer matrix, poly(viny1 chloride), with an oxidant, FeCl,, followed by exposure to pyrrole vapor. The redox properties of films of the blends obtained by this method were studied by cyclic voltammetry and impedance spectroscopy. The results sh
