The cation exchange resins are synthesized from p-phenolsulfonic acid, formalin, and sodium hydroxide catalyser, and the ion exchange properties of them are studied with respect to their reactant ratios. Maximum exchange capacity was 2.06 me/G, much smaller than the theoretical value of 3.42 me/G to be expected for that of the structure: Under the present experimental conditions, much -SO3H radical should have been split away.
