| Zusammenfassung: | The present invention is directed to conductive polymer composition that have positive temperature coefficients, electrical devices comprised thereof and methods of making the same. The composition comprises a thermoset polymer matrix containing discretely distributed thermoplastic material and dispersed conductive material. Preferably, the thermoset and thermoplastic polymers are substantially immiscible and have comparable volume transition temperatures, such as bisphenol A liquid epoxy resins and oxidized polyethylene. |
