Poly(trimethylene terephthalate) (PTT) is an excellent fiber material. Its thermal degradation and isothermal crystalline behaviors were in this study investigated using thermogravimetric analysis (TGA), thermogravimetric analysis-Fourier transform infrared spectroscopy (TGA-FTIR) analysis, differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The thermal degradation mechanism of PTT follows Mclafferty rearrangement principle. The PTTwith intrinsic viscosity (IV) of 0.74 dl/g has a maximum crystallinity of about 55% at 190℃, as demonstrated by DSC and XRD measurements consistently.
