COATED CATION EXCHANGE RESIN AND MANUFACTURE THEREOF

摘要

A cation exchange latex is formed including dispersed fine soluble synthetic resin layering particles with strong acid (e.g. sulfonate) cation-exchanging sites at least on their exposed surfaces. Such as latex is contracted with insoluble resin support particles with strong base anion exchange sites at least on their exposed surfaces to form an ion exchange composition in which the layering particles are irreversibly attached as a monolayer to the support particles.
