摘要

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 metho d 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.
