temperature (Tg).We observed an offset of the tan d peak maximum
to a lower temperature, and the peak became larger and lower. The
peak position is related to the crosslink density of the polymer, and
the peak height and width are related to chain mobility [26]. The
predominant phenomenon that can be observed is an increase of
the mobility, which is highlighted by the offset of the peak to lower
temperatures and modification of the peak width. These data are
consistent with a mechanism that involves chain-scissions
