Abstract
The isothermal and non-isothermal crystallization of poly(ethylene terephthalate) (PET) samples with different thermal histories, i.e., quenched from the melt and annealed below or above Tg, was studied by FT-IR and DSC. Annealing glassy PET below or above Tg accelerated crystallization. The crystallization rate of PET increased with annealing temperature at the same annealing time and annealing time at the same annealing temperature. However, annealing below or above Tg had very little effect on ultimate degree of crystallinity in isothermal or non-isothermal crystallization.
