abstract = {We apply the methodology and concepts developed over the
past years for the study of segmental dynamics on miscible
polymer blends to the investigation of a blend made of
styrene–butadiene rubber (SBR) and an oligomer of
polystyrene (PS) as an example of a simplified industrial
system. In this way we obtain detailed information about the
segmental dynamics of both components within the blend. To
this end, a judicious combination of broad-band dielectric
spectroscopy (BDS) and quasi-elastic neutron scattering
(QENS) results on deuterium-labeled blends was required.
Difficulties on the comparison between isotopically
different samples arose due to changes in polymer
microstructure associated with the obtention of deuterated
polymers. Nevertheless, the strategy for data analysis
developed in this work made it possible to readily resolve
the components’ segmental dynamics of the investigated
mixtures. It was found that Gaussian distributions of the
components’ effective glass-transition temperatures
provide a very good description of all the experimental data
collected in the SBR/PS (50/50 wt $\%)$ mixtures over the
whole accessible temperature range, not only by BDS and QENS
but also those obtained by differential scanning calorimetry
and by neutron elastic fixed window scan experiments.},
