Heat Capacity Relaxation during Annealing of Poly(ethylene oxide) Crystals

Time dependence of the heat capacity of poly(ethylene oxide) crystals during isothermal annealing has been measured with TM-DSC operated in the quasi-isothermal mode. It was found that the relaxation of the heat capacity was composed of two components, that is, fast and slow components. The relaxation time of the slow component was five to ten times as long as that of the slow component. These two components were attributed to melting of thin crystals and lateral growth of the lamella crystals.
