2.sci还未检索 1.FN ISI Export Format VR 1.0 PT J AU Li, GJ Mu, XW Fan, SR Ren, XL AF Li, Guijuan Mu, Xingwen Fan, Shourui Ren, Xiuli TI Study on the Non-isothermal Melt Crystallization Kinetics of PTT/PBT Blends SO JOURNAL OF MACROMOLECULAR SCIENCE PART B-PHYSICS AB Macro-kinetic models, namely the modified Avrami, Ozawa, Mo, and Kissinger models, were applied to investigate the non-isothertnal melt crystallization process of PTT/PBT blends by DSC measurements. It was found that the modified Avrami model can describe the non-isothermal melt crystallization processes of PTT/PBT blends fairly well. When the cooling rates range from 5 to 20 degrees C/min, the Ozawa model could be used to satisfactorily describe the early stage of crystallization. However the Ozawa model didn't fit the polymer blends in the late stage of crystallization, because it ignored the influence of secondary crystallization. Under the conditions of the non-isothermal melt crystallization, it was found that the cooling rates and the blend composition affect the crystallization for blends according to Kissinger crystallization kinetics parameters. The crystallization kinetics constant K-a increases with increasing cooling rate, indicating the crystallization rates of PTT, PBT, and PTT/PBT blends were improved The crystallization kinetic activation energy parameters are good agreement with the results from isothermal crystallization processes of the polymer blends. The crystallization activation energy of PTT/PBT blends is higher than the activation energy of PTT and PBT.
