Abstract
Samples of polystyrene and styrene glycidylmethacrylate copolymer latexes were characterized by Sedimentation Field-Flow Fractionation (SFFF), electron microscopy and by the use of quasi-elastic light-scattering. SFFF makes possible the most complete characterization of particle size distribution of the analyzed samples. Its high selectivity, speed and casual possibility to use the obtained fractions for other analysis or for physico-chemical study belong to its advantages. A two-peak distribution curve was found for one of the studied samples by SFFF. The mechanism of polymerization of this sample could be deduced on the basis of this curve. No other of the compared methods was able to reveal the course of this distribution curve.
