생산 방법Polacrilin resin (Amberlite IRP-64) is prepared by the copolymerization of methacrylic acid with divinylbenzene (DVB). Polacrilin potassium (Amberlite IRP-88) is then produced by neutralizing this resin with potassium hydroxide. Other resins are similarly produced by copolymerization between styrene and divinylbenzene (Amberlite IRP-69, Amberlite IRP-67, Amberlite IR-120, and Amberlite IRA-400). Phenolicbased polyamine condensates (Amberlite IRP-58) may also be produced. The homogeneity of the resin structure depends on the purity, nature, and properties of the copolymers used as well as the controls and conditions employed during the polymerization reaction. The nature and degree of crosslinking have significant influence on the physicochemical properties of the resin matrix. The functional groups introduced on the matrix confer the property of ion exchange. Depending upon the acidity or basicity of the functional groups, strongly acidic to strongly basic types of ion-exchange resins may be produced.
