【Abstract】 By means of DSC, the non-isothermal crystallization kinetics of UV-rcsistant PET were studied. The results show that the screening agent acts as crystal nucleus in the crystallization process of PET, and that the Avrami index n and the crystallization rate increase as the content of screening agent increasing.更多还原
