SummaryA novel rigid spherical biporous poly(glyciclyl methacrylate-triallyl isocyanurate-clivinyJbenzene) resin (denoted Resin B) has been fabricated by radical suspension copolymerization, with superfine granules of calcium carbonate, and toluene and n-heptane, as porogenic agents, as the basis of a novel porogenic mode, cooperation of solid granules and solvents. The pore structure, static adsorption behavior, and chromatographic properties of Resin B were characterized and compared with those of Resin A (with only solvents as porogens). The results indicated that the biporous resin is a promising chromatographic medium for highspeed protein separation with good mechanical performance and high dynamic adsorption capacity ancl column efficiency at high flow rates.
