A novel aliphatic sulfonie acid ion exchange resin was prepared from ethylenediamined polystyrene(PS-acyl-EDA),2-acrylamido-2-methylproanesulfonic acid(AMPS)by Michael reaction.This kind of resin has a longer chain than conventional sulphonic polystyrene resin,that is,the former is easier to react with other compound.The effect of the reaction time,reaction temperature,catalyst amount,reagent amount and the charge ration on reaction result were discussed.Under the optimum condition,the maximum loading of the sulfonie acid ion exchange resin could be up to 1.15 mmol·g-1 resin.The product was characterized with FT-IR.The filling material of chromatographic column could be prepared by this method.
