A comparative dielectric study is reported on the dynamics of a glass-forming epoxy resin when the glass transition is approached through different paths: cooling, compression, and polymerisation. Deep similarities are observed in dynamic properties. A unified reading of the experimental behaviour of the structural relaxation time of chemically reacting and stable systems close to the glass transition is given in the framework of the Adam-Gibbs theory of configurational entropy.

Abstract
A comparative dielectric study is reported on the dynamics of a glass-forming epoxy resin when the glass transition is approached through different paths: cooling, compression, and polymerisation. Deep similarities are observed in dynamic properties. A unified reading of the experimental behaviour of the structural relaxation time of chemically reacting and stable systems close to the glass transition is given in the framework of the Adam-Gibbs theory of configurational entropy.File in questo prodotto:
