The antistatic functional material of HDPE/coal [high density polyethylene mixed with coal fines] has a higher tensile strength, higher resistance and stability. The rheological properties of the blends are important for their processing and practical use. It was necessary to study the rheological behavior of the blends. P. Ujas et al (1994) had studied the rheology of HDPE/nylon-11 blends and the effect of nylon-11 on the rheological behavior of HDPE. If Shenfu coal is used as a special polymer, it has necessarily an important affect on the rheological behavior of HDPE. In this paper, the rheological behavior of HDPE/coal blends were investigated to study the effect of the coal polymer on the rheology of HDPE. The rheological behavior of the blends were found to be very different from that of HDPE. The curves of shear viscosity for the blends at different temperatures (478, 488, and 498K) reveal that HDPE and the blends are characteristic of pseudoplastic fluid, that is, there is a decrease of shear viscosity with an increase of shearing rate.
