Reversible Melting and Poor Crystals

Poly(oxyethylene). The reversing melting of a poorly crystallized oUgomer of poly(oxyethylene) with mass 1500 Da is analyzed in Fig. 6.35 with quasi-isothermal TMDSC. A comparison of this sample with a standard DSC trace is shown in 

Lissajous figures at a temperature close to the reversing melting peak in Fig. 6.35 are plotted in Fig. 6.38 with modulation at different amplitudes, A. Larger-scale melting and crystallization can be seen as soon as A covers the region from a finite melting rate to a finite crystallization rate, as is indicated in Fig. 3.76. Closer
