The normalized dynamic master-curves of G0 and G00 can be seen
in Fig. 1. All data fell into a single master-curve in reasonable
approximation. The plateau modulus (GN
0 ), used as a normalization
factor, is a viscoelastic parameter defined for polymers as the
extrapolation of the entanglement contribution to the viscoelastic
functions at high frequencies (Larrosa et al., 2015). The fact that
these master-curves could be achieved by applying an empirical
vertical superposition method implies that the different compositions
did not modify the overall microstructural pattern of systems,
but mainly influenced the level of interactions among macromolecular
components.
