A comparative study is reported on the dynamics of a glass-forming system when the glass transition is approached through different paths: cooling, compression, and polymerization. In particular, the influence of temperature, pressure and connectivity on the dynamics has been investigated by dielectric spectroscopy. A phenomenological description of the behavior of the dielectric response shows the existence of both differences and deep similarities between the change of some dielectric parameters during a polymerization reaction and during the temperature or pressure changes.

Abstract

A comparative study is reported on the dynamics of a glass-forming system when the glass transition is approached through different paths: cooling, compression, and polymerization. In particular, the influence of temperature, pressure and connectivity on the dynamics has been investigated by dielectric spectroscopy. A phenomenological description of the behavior of the dielectric response shows the existence of both differences and deep similarities between the change of some dielectric parameters during a polymerization reaction and during the temperature or pressure changes. A unified reading of our experimental results can be given in the framework of the Adam-Gibbs theory.
