A method of data manipulation using the dynamic magnitude spectrum and the static absorbance spectrum is applied to uniaxially drawn poly(ethylene terephthalate) films with five different draw ratios for the evaluation of the amplitude of dynamic structural changes under a sinusoidal strain at the level of a functional group. This analysis revealed that, in the drawn film, the skeletal structures, such as the C–O bond in the ethylene glycol unit and the phenyl ring, are susceptible to deformation by mechanical stretching, while the dynamic structural changes around the methylene group are small. It was assumed that the backbone of the polymer is responsible for the change of the mechanical properties induced by the drawing of the film.

Pet Film

Dynamic FT-IR spectra of uniaxially 5×-drawn poly(ethylene terephthalate) (PET) film at a temperature of 30 to 150 °C were measured with the use of a variable-temperature polymer stretcher, and amplitude spectrum analyses of the dynamic spectra were carried out. A drastic decrease in dynamic variations of the trans C–O stretching band was observed above the glass-to-rubber transition temperature. This observation suggests that the trans C–O bond in the ethylene glycol unit is closely related to changes in macroscopic mechanical properties of PET film in the glass-to-rubber transition.
