Fig. 92: X-ray speckle pattern from PS-PI block copolymer micelles dispersed in a PS matrix taken with a CCD detector at 293 K (top) and 393 K (bottom). The grainy appearences of the (top) pattern below the glass transition temperature of PS (Tg ~ 360 K) disappears when the sample is heated above Tg (bottom).
