Seeded porous copolymers and ion-exchange resins prepared therefrom

摘要: The invention concerns preparation of porous copolymer beads by a seeded polymerization process employing gel seed particles. comprises initially providing plurality gel-type particles prepared at least one first monovinylidene monomer and cross-linking monomer. A second mixture comprising monomer, phase-separating diluent is thereafter imbibed the polymerized therein. characterized selecting monomers such that are capable being in an amount sufficient to form copolymer. produced have stable polymeric structures good physical properties render them useful preparing ion-exchange resins adsorbents.
