Viscosity measurements were repeated at least three times for each sample, and more measurements were carried out in those cases in which standard deviations greater than 0.1 s in the flow times were obtained.
The kinematic viscosity in each case was calculated as the product of the calibration constant of the specific capillary (certified by the manufacturer) and the average flow time.
Subsequently, the dynamic viscosity was obtained as the product of the kinematic viscosity and the density of each sample at each temperature.
