Original Abstract
The current knowledge of polystyrene (PS) sulfonation was reviewed. The experimental part of this work was focused on preparation of the water-soluble PS. The kinetic parameters of both homogeneous and heterogeneous sulfonation were studied. The main attention was focused on the study of heterogeneous sulfonation of solid PS using gaseous SO3 diluted with air. The influence of temperature, Mw of starting PS, specific surface area of solid PS particles and their morphology on the mechanism and kinetics of heterogeneous sulfonation were investigated. The sulfonated PS samples were characterized using elemental ICP analysis, alkalimetric titration, EDAX microanalysis, FT-IR spectroscopy and SEM measurement. The preliminary application of surface sulfonated foamed PS and water-soluble sodium salt of polystyrenesulfonic acid to concrete samples was attempted.
