Electrically conductive immiscible polymer blends containing high impact polystyrene (HIPS), liquid crystalline polymer (LCP) and a low content of conductive carbon black (CB) were studied to establish and understand the correlation between composition, electrical properties and the morphology of filaments produced at different melt flow conditions. The HIPS/LCP/CB blend containing 30% LCP and at least 2 phr CB reveals a stable resisitivity throughout the shear rate range applied in a capillary rheometer. Interesting structure alterations were observed for the LCP and CB components as a result of melt flow processing. Unusual sensing properties of liquids were found for the blends containing LCP.
