Abstract
The dynamics of an epoxy compound has been studied by wideband dielectric spectroscopy and light scattering above the glass transition temperature, Tg. A change of diffusion mechanism in the supercooled liquids has been recognized some tens of degrees above the glass transition, where a change in the temperature behavior of the main relaxation time occurs, together with the splitting of the structural and secondary relaxations and deviation from the Stokes-Einstein-Debye diffusion law. The light scattering results can be interpreted in terms of a correlation length for the structural relaxation which increases for decreasing temperature.
