Abstract
The ionic resins, amphoteric type, having both cationic and anionic group were prepared by introducing sulfonyl chloride group into a poly (styrene-co-divinylbenzone) letting it reacted with ethylamine, diethylamine, aniline, and diphenylamine in the presence of aqueous alkali, respectively, The polymer matrix was obtained by using suspension polymerization, and modified with chlorosulfonic acid. The reactivity of chlorosulfonated resin toward amine and Arrhenius alkali was studied by cationic capacity and elemental analysis data. And pilysicochemical properties of prepared amphoteric resins were also studied. It was observed that cationic ant anionic exchange capacity of prepared resins were 1.84-3.20 meq./g and 1. 1-1.5 meq./g, respectively, But these capacities could by regulated by treating the final product with strong acid, and more presumably by controlling amine/alkali ratio while preparing the resins.
