description | We synthesized Poly(decamethylene sebacate) - P10MS - and studied its overall crystallization rates in a range of temperatures using Differential Scanning Calorimetry in isothermal conditions, which enabled us to identify the crystallization mechanism by means of the Johnson-Mehl-Avrami-Kolmogorov equation. The critical cooling rate (Rc) to vitrify the P10MS was determined using a non-isothermal method proposed by Barandiarán & Colmenero (BC). The value of Rc is around 50-250 K/s, which confirms the experimentally observed difficulty to vitrify this polymer. |
