It is proposed to derive the Williams-Landel-Ferry equation for the temperature dependence of the viscosity η(T) in the glass transition region, which, unlike the known approaches, is not associated with a specific functional dependence η (T) and is of a General nature. Our task is limited to the first three terms of decomposition. The detailed conclusion with all intermediate transformations is carried out.
