| Résumé : | The complex melting behaviour and crystallization kinetics of polyhexamethylene terephthalate (PHT) and its copolymers with isophthalic acid (PHT col) have been explored using differential scanning calorimetry (DSC) and simultaneous time resolved synchrotron radiation wide angle and small angle X-ray scattering (WAXS and SAXS). Special attention has been paid to the presence of isophthalic chain defects and to crosslinking on the rate of crystallization. Kinetic data have been tentatively analyzed using Avrami parameters for the global crystallization and the Hoffman-Lauritzen equation for the separation of the factors governing spherulite growth rate. |
