Nature of the Glass Transition and the Glassy State

摘要: The thermodynamic properties of amorphous phases linear molecular chains are obtained from statistical mechanics by means a form the quasi‐lattice theory which allows for chain stiffness and variation volume with temperature. A second‐order transition is predicted these systems.This has all qualitative features glass observed experimentally. It occurs at temperature an increasing function both length decreasing free volume.The ``relaxation times'' shown to increase rapidly as approached above.To permit quantitative application determine relationship between in ``slow'' experiments two transitions tentatively identified. By this predictions made concerning variations (1) molecula...
