Abstract

Macroporous polymers having selected porosity and permeability characteristics that provide rigid polymer matrices suitable for use in medium and high pressure reversed phase liquid chromatography (RPC) are disclosed. A method for preparing the polymers using selected mixed porogens in selected proportions relative to the monomer phase is also disclosed. The polymers are especially useful as stationary phases in large scale chromatography columns without developing increased pressures during prolonged use, while maintaining good chromatographic performance for targeted biomolecules, such as insulin.
