A modified isoconversional method is applied to perform the kinetic analysis of non-isothermal processes. The solidification
process of a polyethylene glycol with a mean molecular of 4000 (PEG 4000) was here analyzed. It was stated that the Avrami
model provides a good description of the solidification process.
Temperature-cooling rate-transformation diagrams were constructed and there was a good agreement between experimental data
and the calculated T-CR-T curves. Moreover, morphological qualitative analysis has been performed by means of scanning electron
