T‐CR‐T diagrams are one of the most reliable ways to predict the thermal behavior of material solidification from the melt. A brief description of solidification accounting for continuous cooling is presented for fast‐crystallizing polymers. An isoconversional method is applied to the kinetic analysis of non‐isothermal processes. The solidification process of different polymer materials: high density polyethylene based samples and mixtures of PEG with a pharmaceutical drug were analyzed by means of DSC. Several diagrams were constructed and the best agreement between experimental data and the calculated T‐CR‐T curves corresponds to the use of the isoconversional method.
