In this study, one new function is defined as change of relative crystallization degree in unit time and named relative crystallization rate (1/min.). The curve of heat flow rate to time is transmitted to that of to . The produced curve was fitted using one high-order polynomial equation with a variable of and the coefficient vector (Ai ,in this paper,the values of i were from 0 to 9)was produced. It was found that, even during the accelerated stage of crystallization from PET melt,both aspects to promote and delay the relative crystallization rate existed, furthermore, both aspects of promotion and delay declined with the crystallization process and appeared “internal exhaustion”.
