    After 200 hours of milling a halo pattern dominated. The result, therefore, led us to conclude that the amorphization of the PVA was caused by the mechanical destruction of the crystal structure. The amorphization of the PVA was also confirmed through the observation of low energy excitation by inelastic neutron scattering.
