      abstract     = {We investigate concentrated solutions of
                      poly(styrene-b-N-isopropyl acrylamide) (P(S-b-NIPAM))
                      diblock copolymers in deuterated water (D2O). Both
                      structural changes and the changes of the segmental dynamics
                      occurring upon heating through the lower critical solution
                      temperature (LCST) of PNIPAM are studied using small-angle
                      neutron scattering and neutron spin-echo spectroscopy. The
                      collapse of the micellar shell and the cluster formation of
                      collapsed micelles at the LCST as well as an increase of the
                      segmental diffusion coefficient after crossing the LCST are
                      detected. Comparing to our recent results on a triblock
                      copolymer P(S-b-NIPAM-b-S) [25], we observe that the
                      collapse transition of P(S-b-NIPAM) is more complex and that
                      the PNIPAM segmental dynamics are faster than in
                      P(S-b-NIPAM-b-S).},
