An increase
in temperature was seen both to decrease the values of both
moduli and cause notable changes in the shape of the mechanical
spectra obtained. Thus, at room temperature, samples show a viscoelastic
behaviour typical of a transition from the glass to the rubbery
region. This viscoelastic behaviour, characterized by both
moduli showing similar slopes, suggests a highly elastic material
and the development of a three-dimensional network structure
that involves a large amount of interactions among chain
segments.
