Abstract We investigate systems benzene in polystyrene as model for binary glass formers by applying multidimensional 2 H NMR experiments. It is demonstrated that the molecular larger component of these systems essentially behaves as a neat glass former, whereas the small benzene molecules show a completely different scenario. Their 6-fold axes still reorientate isotropically below the glass transition of the mixed system. This dynamics is characterised by a very broad distribution of… CONTINUE READING
