A new conducting composite of polypyrrole (PPy) has been prepared electrochemically where polytetramethylbisphenol A carbonate is used as the insulating matrix polymer. Characterization of the freestanding films of the composites were based on scanning electron microscopy, differential scanning calorimetry, and Fourier transform infrared studies as well as electrical conductivity measurements and solubility. Electrical conductivities were measured by a four‐probe technique. Spectroscopic methods, together with conductivity and solubility studies, indicate that the synthesized composite is a homogeneous blend of the two polymers. No evidence of hydrogen bonding in the composite or grafting of the two polymers has been found, contrary to the PPy‐polybisphenol A carbonate case. © 1996 John Wiley & Sons, Inc.
