It has been shown that using the dependence of catalytic activity of ion exchangers on the degree of sulphonation one can infer on the structure of their polymeric skeleton. Using condensation of phenol and acetone yielding Bisphenol A as a test reaction we have been able to distinguish up to four fractions of active groups in a series of ion exchangers of the gel and macroreticular type affected to a different extent by the structure of the surrounding polymer mass.
