A Study of the Deformation, Network, and Aging of Polyethylene Oxide Films by Infrared Spectroscopy and Calorimetric Measurements

Figure 2

Transition spectra at 60°C: The two regions show more bands than those observed in the solid and the melt (Figure 1(b)). (a) The 1400–1200 cm⁻¹ interval (with eight bands). (b) The 1070–875 cm⁻¹ interval (with six bands). Note the small band at 956 cm⁻¹.
