Abstract

An electrically conductive polymer composition containing a polymer mixture containing a first crystalline polymer having a weight-average molecular weight of at least 50,000 and a second crystalline polymer having a weight-average molecular weight of at most 10,000, and a particulate electrically conductive filler has good processability and exhibits a low resistivity at 20 °C and a good positive temperature coefficient (PTC) behavior.
