Interest in bottlebrush polymers continues to grow. In these comb polymers, the high grafting density of side chains seems to be responsible for exceptional macroscopic properties, like hyper-elasticity or ultralow viscosity. This behavior makes this class of polymers particularly interesting for fundamental studies. Bottlebrush polymers seem to be an ideal material, because backbone and sidechain can be independently controlled. Most of the studies on this highly customizable polymer concentrate on the material behavior. Much less is known about the microscopic conformation and dynamics.<br/> <br/>Here we present first studies on the dynamics of bottlebrush polymers at the length scale of a few nanometers. This presentation reports on recent neutron spectroscopy results on the dynamics of side chains. We show how the dynamics at the very local scale relates to the macroscopic material properties.
