LARGE-PORE CHROMATOGRAPHIC BEADS PREPARED BY SUSPENSION POLYMERIZATION |
摘要 |
Chromatographic beads with pores large enough to serve as through-channels for fast diffusion and a substantial absence of pores of smaller diameters that would cause band broadening due to slow diffusive transport, are formed by suspension polymerization of an aqueous solution of a monomer mixture that includes a total monomer (combination of polymer backbone monomer and crosslinking agent) concentration of 2 % to 50 % by weight relative to the aqueous solution and a crosslinking agent in an amount such that the mole ratio of crosslinking agent to total monomer is from about 0.1 to about 0.7. The suspension polymerization process involves forming a suspension of aqueous droplets of the monomer mixture in an organic phase.
