Letter

After successfully being commercialized in the 1990s, poly(trimethylene terephthalate) (PTT) has drawn more and more attention due to its superior characteristics, such as elastic recovery, chemical resistance and resilience in comparison with poly (ethylene terephthalate) (PET) and poly (butylene terephthalate) (PBT) [1, 2]. PTT is a typical semicrystalline polymer material and many reports were focused on its crystallization behaviors recently. Huang and Chang [3] investigated the crystallization behavior for PTT from the melt and analyzed the kinetics in the temperature range from 451 K to 483 K, some important parameters for crystallization such as equilibrium melting temperature(Tm0 = 521 K), lateral surface-free energy (σ),work of chain folding (q) were also reported. Crystallization kinetics parameters of PET, PTT and PBT were compared by Chuah [4], it could be concluded that PTT crystallized faster than PET but slower than PBT at the same degree of undercooling. Hong and his...
