CRITICAL OPALESCENCE OF POLYSTYRENE IN CYCLO-HEXANE TRANSMISSION MEASUREMENTS
Abstract
IN THE VICINITY OF THE CRITICAL POINT, ANGULAR DISSYMMETRY OF SCATTERING IS OBSERVED. Its amount is connected with the range of molecular forces. Integrated over all angles it reveals that the total scattering is less than that calculated according to Einstein. At the same time the scattered light is less blue than anticipated according to Rayleigh. This effect was investigated on the system polystyrene-cyclohexane by measurements of the wavelength dependence of the total turbidity of the solution at its critical concentration as a function of the temperature. The interaction range as calculated from the data is in good agreement with values calculated from dissymmetry measurements. (Author)
