Glass transition of an epoxy resin induced by temperature, pressure and chemical conversion: a rationale based on configurational entropy

S. Corezzi, D. Fioretto, R. Casalini, P.A. Rolla

Abstract

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.
