A Molecular Approach to the Problem of Viscoelasticity


IN a previous communication1, one of us made a tentative attempt to interpret the rheological behaviour of hydrogen-bonded solids in terms of their molecular and thermodynamic parameters. This theory was elaborated in a later publication2, in which evidence from a number of sources was adduced for its validity. Further evidence was obtained from other sources showing that the theory was acceptable3,4. However, the evidence presented in these papers was indirect. We wish to report here a more direct confirmation of the major hypothesis made in this theory.
