      abstract     = {The thermoresponsive behavior of a poly(2-oxazoline)-based
                      molecular brush is investigated in aqueous solution. The
                      molecular brush under study, PiPOx100-g-PEtOx17, has a
                      poly(2-isopropenyl-2-oxazoline) (PiPOx) backbone grafted
                      with thermoresponsive poly(2-ethyl-2-oxazoline) (PEtOx) side
                      chains. Since the backbone degree of polymerization is only
                      a factor of ~ 6 higher than the ones of the side chains,
                      it features an architecture between a star-like polymer and
                      a comb-like polymer. Its aqueous solution exhibits lower
                      critical solution temperature (LCST) behavior with a cloud
                      point temperature Tcp = 40.5 °C at 30 g L−1. The
                      temperature-dependent structural evolution is disclosed
                      using dynamic light scattering (DLS) and small-angle neutron
                      scattering (SANS). An increase of the molecular brush size
                      is found upon heating from room temperature to Tcp, which is
                      attributed to the extension of the backbone resulting from
                      the dehydration and collapse of the side chains. Above Tcp,
                      the size decreases again, which indicates the collapse of
                      the whole molecular brush. Large aggregates are found to be
                      present in the solution in the temperature range 25–50
                      °C. These become more compact, as the temperature is
                      increased across Tcp.},
