Sažetak
An extensive and more complete study of light scattering of three BASF and eight Dow polystyrene latexes was undertaken. The measurements were performed at four wavelengths of the mercury arc, and theoretical functions, published in a foregoing paper, were applied. Five different methods of determination of particle size by light scattering were used: transmission, scattering at 90°, dissymmetry, polarization ratio, and positions of maxima and minima in angular distribution. The results are in good agreement with earlier data obtained on some of the latexes investigated in this work. It was found that the particle sizes are generally smaller than those obtained by electron microscopy. Any definitive explanation of this behavior could not be found.
