An insulating polymer was retained in the blend and the thermal stability of the polymer was enhanced by polymerizing pyrrole into the host matrix in both cases. The composites prepared electrochemically gave the best results in terms of conductivity and air stability. © 1997 John Wiley * Sons, Inc.EnglishElectric conductivity of solidsElectric insulating materialsElectropolymerizationNonmetallic matrix compositesPolymer blendsPolyvinyl acetatesPolyvinyl chloridesThermodynamic stabilityPolypyrroleCopolymersArticle10.1002/(SICI)1097-4628(19970425)64:4<667::AID-APP5>3.0.CO;2-L
