Summary
It has been found that the three-phase heterogeneous reaction of propane sultone with hydrolyzed macroporous glycidylmethacrylate copolymers in an aqueous alkaline medium proceeds to a higher degree in presence of phase transfer catalyst. The best results were obtained using tetra(n-butyl)ammonium hydroxide. An important finding is the increase in the degree of transformation of the reaction in flow arrangement compared with the batch procedure. The influence of phase transfer catalyst is also more effective. The reaction is discussed with respect to the properties of the products, i.e. of the overall and surface contents of groups introduced into the reaction, of the specific surface area and specific pore volume of sulfopropylated copolymers.
