The effect of aging following different treatments on the high frequency dynamics of a polymeric glass was measured by means of low frequency Raman scattering and inelastic neutron scattering. The spectra, in particular the Boson peak, are consistent with the discontinuous network model at the nanometric scale. The effects of similar aging procedures on slow dynamics are investigated by low frequency mechanical spectroscopy. The set of results is discussed within a multiscale description of the glassy state disorder.
