Abstract

Poly(ethylene terephthalate)(PET) with different cyclic oligomer contents was crystallized under isothermal condition. Crystallization rate has been determined by differential scanning calorimetry(DSC). All the data obtained through DSC were treated with Avrami's equation. Some parameters for crystallization kinetics were derived. It was found that the cyclic oligomer contained in PET retards the crystallization rate. This finding was confirmed by observing the morphology of PET with polarizing microscope.
