The structure/electrical resistivity relationship in CB-loaded immisci
ble HIPS/LLDPE blends was studied. Effects of CB content and location,
dispersed polymer phase size and shape, dispersed phase viscosity, an
d processing procedures were examined. The elongated dispersed phase i
n CB-containing blends is essential for promoting conductivity in form
ulations prepared by melt mixing and compression molding. However, the
same formulations proved highly resistive when injection-molded, due
to orientation and excessive shearing. (C) 1997 John Wiley & Sons, Inc
