A comparative study is reported on the dynamics of a glass-forming epoxyresin when the glass transition is approached through different paths: cooling,compression, and polymerization. In particular, the influence of temperature,pressure and chemical conversion on the dynamics has been investigated bydielectric spectroscopy. Deep similarities are found in dynamic properties. Aunified reading of our experimental results for the structural relaxation timeis given in the framework of the Adam-Gibbs theory. The quantitative agreementwith the experimental data is remarkable, joined with physical values of thefitting parameters. In particular, the fitting function of the isothermaltau(P) data gives a well reasonable prediction for the molar thermal expansionof the neat system, and the fitting function of the isobaric-isothermal tau(C)data under step- polymerization conforms to the prediction of diverging tau atcomplete conversion of the system.
