3.3.2. Rheological modules
Figs. 4 and 5 represent the effects of independent variables (PO,
XG, DMG, and CB) on G and G, respectively. The results showed
that XG and PO had the greatest impact on G and G, respectively.
According to the Figs. 4 and 5, increasing XG concentration
resulted in an increase in both modules. When volume fraction of
PO was increased, both modules dropped. The DMG had adverse
impact on G and G. The CB concentration had the least effect on
them. The intersecting frequency gives valuable information about
rheological properties of spreads. The crossover frequency (where
