We present a dielectric relaxation spectroscopy study of the dynamics in the thermoreversible polymer gel system atactic polystyrene/toluene. We observe three distinct relaxational process, the α‐ and β‐relaxations related to solvent dynamics and a process related to the dynamics of the polymer network. While both the α‐relaxation and the network processes are slowed down with increasing polymer content, the β‐relaxation remains practically unchanged. The behaviour of the relaxational process related to the polymer network, shows no distinct change at gelation, suggesting that there are no major changes taking place in the polymer network on the length scale of the observed relaxation. Furthermore, it is possible to construct a master curve of the temperature dependence of the relaxation time of the matrix relaxation by a simple temperature scaling.
