After an equilibration period of 5 min at 55 ◦C (6.28rad/s),frequency sweeps were performed over the range 1 to ∼63 rad/s.Finally, flow curves were recorded at 55 ◦C by using a steady state
flow ramp with a considered maximum range of shear rates of 1–1000 s−1. The shear rate was recorded point by point with a maximum point time of 1 min.The curves were built from viscosity
data determined for each point as an average of three consecutive measurements with a maximum 5% deviation.
