Abstract
A conductive polymeric blend comprises an intrinsically conductive polymer, an insulating thermoplastic material and at least one additive selected from the group consisting of an impact modifier, an ester-free plasticizer and an acidic surfactant. The thermoplastic material comprises a thermoplastic polymer. The conductive polymeric blend has a conductivity of greater than about 10.sup.-9 S/cm. A process for preparing conductive polymeric blends comprises the steps of forming a blend comprising an intrinsically conductive polymer, an insulating thermoplastic material and at least one additive selected from the group consisting of an impact modifier, an ester-free plasticizer and an acidic surfactant. The thermoplastic material comprises a thermoplastic polymer. The conductive polymeric blend has a conductivity of from of greater than yabout 10.sup.-9 S/cm.
