Study on Non-isothermal Crystallization Kinetics of PBT with High Melt Flow Index

摘要

The non-isothermal crystallization process of PBT with high melt flow index has been investigated by DSC, and the non-isothermal crystallization process of PBT with high melt flow index was studied by Ozawa equation and Jeziorny equation respectively. It was found that Ozawa equation, rather than Jeziorny equation, could appropriately be applied to study the non-isothermal crystallization process of PBT with high melt flow index. The Avrami index, obtained by Ozawa equation, varied between 1.06-1.80 with the change in temperature.
