      abstract     = {We review recent neutron scattering work and related
                      results from simulation and complementary techniques
                      focusing on the microscopic dynamics of polymers under
                      confinement. Confinement is either realized in model porous
                      materials or in polymer nanocomposites (PNC). The dynamics
                      of such confined polymers is affected on the local segmental
                      level, the level of entanglements as well as on global
                      levels: (i) at the segmental level the interaction with the
                      surface is of key importance. At locally repulsive surfaces
                      compared to the bulk the segmental dynamics is not altered.
                      Attractive surfaces slow down the segmental dynamics in
                      their neighborhood but do not give rise to dead, glassy
                      layers. (ii) Confinement generally has little effect on the
                      inter-chain entanglements: both for weakly as well as for
                      marginally confined polymers the reptation tube size is not
                      changed. Only for strongly confined polymers disentanglement
                      takes place. Similarly, in PNC at higher NP loading
                      disentanglement phenomena are observed; in addition, at very
                      high loading a transition from polymer caused topological
                      constraints to purely geometrical constraints is observed.
                      (iii) On the more global scale NSE experiments revealed
                      important information on the nature of the interphase
                      between adsorbed layer and bulk polymer. (iv) Polymer grafts
                      at NP mutually confine each other, an effect that is most
                      pronounced for one component NP. (v) Global diffusion of
                      entangled polymers both in weakly and strongly attractive
                      PNC is governed by the ratio of bottle-neck to chain size
                      that characterizes the ‘entropic barrier’ for global
                      diffusion.},
