摘要：The present invention is directed to conductive polymer composition that havepositive temperature coefficients, electrical devices comprised thereof and methods ofmaking the same. The composition comprises a thermoset polymer matrix containingdiscretely distributed thermoplastic material and dispersed conductive material.Preferably, the thermoset and thermoplastic polymers are substantially immiscible andhave comparable volume transition temperatures, such as bisphenol A liquid epoxy resinsand oxidized polyethylene.
