| 中文摘要 | after isothermal crystallization, poly(ethylene terephthalate) (pet) showed double endothermic behavior in the differential scanning calorimetry (dsc) heating scan. during the heating scans of semicrystalline pet, a metastable melt which comes from melting thinner lamellar crystal populations formed between the low and the upper endothermic temperatures. the metastable melt can recrystallize immediately just above the low melting temperature and form thicker lamellae than the original ones. the thickness and perfection depends on the crystallization time and crystallization temperature. the crystallization kinetics of this metastable melt can be determined by means of dsc. the kinetics analysis showed that the isothermal crystallization of the metastable pet melt proceeds with an avrami exponent of n = 1.0 similar to 1.2, probably reflecting one-dimensional or irregular line growth of the crystal occurring between the existing main lamellae with heterogeneous nucleation. this is in agreement with the hypothesis that the melting peaks are associated with two distinct crystal populations with different thicknesses.
