Non-isothermal crystallization kinetics of bio-based poly(butylene-co-isosorbide succinate) (PBIS)

Crystallization kinetics are very important for polymeric materials due to the fact that they determine the final degree of crystallinity and the morphology of the final product after processing. The kinetic of non-isothermal crystallization of poly(butylene-co-isosorbide succinate) (PBIS) was investigated using differential scanning calorimetry. Ozawa, Jeziorny and Mo methods were used to describe the non-isothermal crystallization process of PBIS. Both the Ozawa constant and the Avrami constant were obtained by Ozawa method and Jeziorny method, respectively. The crystallization activation energy (∆ E ) for non-isothermal crystallization process of PBIS, analyze based on the differential isoconversional method of Friedman and Kissinger, was found to increase with the relative crystallinity.
