Abstract

In this letter we introduced a new scaling method based on Adam-Gibbs model. Moreover, generalised critical-like expression of configurational entropy S_C (T)=S₀ (1-T_K/T)ⁿ is used. Obtained values of pseudocritical exponent n seem to be universal for studied systems and corresponds well with thermodynamic data. Relation between dynamic portrayal represented by primary relaxation time and thermodynamic (specific heat capacity) is in a good agreement.
