Time-resolved dichroic difference spectra

Figure 7 Relaxation of orientation measured simultaneously for both components in miscible PS/PVME blends following a rapid deformation (1 m/s) to a draw ratio of 2 at Tg +15°C. The time-resolved dichroic difference spectra were acquired using PM-IRLD. Reproduced with permission from Pellerin et al. [42]. Copyright 2000 American Chemical Society.

Time-resolved dichroic difference spectra of atactic polystyrene generated from the spectra shown in Figure 21.3 over a little more than one cycle of the stretcher are shown in Figure 21.4, along with the variation of the applied strain over the same period. From this curve, the variation in intensity and phase of each of the bands in the spectrum can be visualized. Under the same scan conditions, it would...
