An Adam‐Gibbs based model for the temperature behavior of polymers near glass transition

Abstract

The mechanical behavior of polymers and other glass forming materials is strongly time-and temperature-dependent. Based on the rheological Poynting-Thomson Model and the Adam-Gibbs equation, a shift function is developed which relates the time constants of a material to temperature. The behavior of this function is compared to the established Williams-Landel-Ferry and Arrhenius equations in the glassy and rubbery temperature regimes.
