| description | The present invention discloses two component cross-linked copolymers in bead form wherein the cross-linked copolymer of the first component formed in the first step has lower cross-linker content than the cross-linker content in the cross-linked copolymer of the second component formed in the second step. These beads are further functionalized to yield strong acid cation exchange resins, strong base anion exchange resins and weak acid cation exchange resins. Ion exchange resins so synthesized exhibit operating exchange capacity (OEC) to total exchange capacity (TEC) ratio in the range of 49 to 61% and also retain more than 85% of whole bead count when subject to osmotic shock resistance test to simulate performance in usage. These ion exchange resins offer advantages in applications such as water treatment, condensate polishing, and unit operations in non-water application like drug purification, sugar processing, catalysis etc. |
