The mechanical characteristics in the region of the primary relaxation have been measured in linear (bisphenol-A-polycarbonate and polyurethane) and reticulated (a fully crosslinked heterocyclic network) amorphous polymers. It is found a correlation between the fragility and anharmonicity of the systems, the most fragile polymer being characterized by the largest anharmonicity. © 2000 American Institute of Physics.
