heal.abstract	Strong cationic resins have been prepared from isoporous polystyrene networks in bead form with H2SO4 and HSO3Cl as sulphonating agents. The effect of the reaction time of H2SO4 sulphonation on ion exchange capacity has been examined. The polymer-solvent interaction parameter, X, with aqueous electrolyte solutions has been calculated after minimization of electrostatic repulsions. The average molecular weight per crosslinked unit, M ̄c has been measured after sulphonation and an estimation of formation of sulphone-type crosslinks has been attempted. The average size of the network structure, rc, has been calculated as a function of the ionic strength of aqueous electrolyte solutions for networks of different molecular weight per crosslinked unit, M ̄c. The ion exchange capacity of the prepared resins has been measured. © 1984.	en
