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

Table 1

Characteristics of the melting traces of the PEO sample in different conditions.

	Ramp; (K/min)	ΔH^a; (J/g)	Tm; (°C)	Tc; (°C)	Events in the melt^b,c
					ΔHrelax; (J/g)	Trelax; (°C)
Standard	5	147	61	46
Nonstandard	0.05	130	68	44	50–100	80–110

^a The value of 𝛼c is found to be 0.72 from ΔH₀ = 204 J/g.
^b The value of ΔH_relax and the range of T_relax are sensitive to the conditions [22–30, 36, 37].
^c The signal in the melt is endothermic for a deformation and exothermic for a relaxation.
