The investigation of dynamic properties of polymeric materials near the glass transition is one of the most important topics in the field of amorphous materials. Many theories were proposed in order to rationalise the dependence of dynamics on temperature, pressure and aging time. In this paper we briefly review recent works where the thermodynamic theory of Adam and Gibbs was successfully applied to reproduce dynamic properties in polymeric systems above and below the glass and discuss the main points of the debate in progress concerning the applicability of the theory.
