The structure/electrical resistivity relationship in CB‐loaded immiscible HIPS/LLDPE blends was studied. Effects of CB content and location, dispersed polymer phase size and shape, dispersed phase viscosity, and processing procedures were examined. The elongated dispersed phase in CB‐containing blends is essential for promoting conductivity in formulations prepared by melt mixing and compression molding. However, the same formulations proved highly resistive when injection‐molded, due to orientation and excessive shearing. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 1097–1106, 1997
