      abstract     = {The tube model for linear and branched architectures is
                      nowadays able to predict in high precision the linear
                      viscoelastic relaxation time spectrum. For linear chains,
                      the involved time scales fit to the commonly accessible
                      dynamic scattering techniques. This makes it possible to
                      microscopically investigate the correlation between
                      structures and relaxation processes. In branched systems,
                      however, the hierarchical nature of relaxations limits
                      direct investigation via these microscopic methods as the
                      dynamic processes are prolongated to much longer relaxation
                      times that are no more accessible to usual dynamic
                      scattering methods. A way to overcome this difficulty is
                      offered by the use of static small angle neutron scattering.
                      Here, the combination of annealing and quenching steps after
                      a step deformation provides unique information of the
                      structure at particular times along the relaxation spectrum.
                      This, however, necessitates the availability of
                      architecturally clean and specifically deuterium labelled
                      model polymers due to the sensitivity of the scattering
                      method. Therefore, we outline in this contribution first the
                      current status on the synthesis and analysis of such
                      compounds with relation to neutron scattering. Secondly, we
                      present exemplary neutron scattering results from in situ
                      stress relaxation studies inside the neutron beam on linear
                      and H-shaped branched polymers which were molecularly
                      designed to highlight specific relaxation processes. We
                      discuss the relevance of the tube model parameters in linear
                      and non-linear studies. (C) 2010 Elsevier Ltd. All rights
