Abstract
Abstract The temperature dependence of the intensity of scattered light has been investigated through the glass transition region. It has been found that within this region a considerable decrease in scattered intensity occurs during cooling. It is shown that on reheating through the glass transition region maxima in the intensity versus temperature curves are observed. Thus hysteresis is found in the behaviour of the light scattering intensity in the glass transition region. This hysteresis is due to the specificity in behaviour of both density and anisotropy fluctuations.
