ABSTRACT:
A method of derivatizing a chromatography matrix having a hydrophobic surface involves reacting the hydrophobic surface with a halosulfonating agent to produce a significant amount of halosulfone groups covalently bonded onto the surface. Sulfonamide bonds then are formed between these halosulfone groups and a group of amine functions on a polyaminated polymer to produce a pellicular anion exchange layer covalently bonded to the surface. The resulting layer is stable in the absence of cross-links between the molecules of the polyaminated polymer.
