Dynamic shear viscosity of high density polyethylene with a low density polyethylene was studied as a function of
HDPE content. Blends were prepared by melt mixing and then oscillatory shear rheology measurements of them carried
out at 190°C. The Complex viscosity functions of blends are laid between the viscosity curves of the components, and
also all blends exhibit a higher shear viscosity than the LDPE. Plot of zero shear viscosity as a function of weight
content of LDPE revealed that 10% and 15% HDPE blends followed linear-additivity mixing rule but 35% and 50%
HDPE blends deviated from the mixing rule.
