Abstract

PURPOSE: To obtain a cation-exchange resin having excellent mechanical strength, potassium selectivity, etc., by sulfonating a resin having ethylenic unsaturations in the main chain or the side chains, and then contacting the product with an aliphatic glycol.
CONSTITUTION: The resin of the purpose, having a cation-exchange capacity, is obtained by sulfonating a resin having ethylenic unsaturations in the main chain and/or the side chains, such as natural rubber, polyisoprene, 1, 2-polybutadiene or polychloroprene with a sulfonating agent such as conc. sulfuric acid, chlorosulfonic acid or fuming sulfuric acid; contacting the resulting viscous sulfonated resin solution with an aliphatic glycol such as ethylene glycol, propylene glycol or polypropylene glycol, to separate the sulfonated resin in the form of particles from the reaction solution; and filtering, washing and drying the separated resin.
