<p>The process for making entails forming a droplet of water, cyclodextrin and base in a non-polar solvent such as methylisobutylketone using polyvinyl butyral as an emulsifier. A cross-linking agent such as epichlorohydrin is reacted with the cyclodextrin to form a spherical bead having a surface substantially free of chemically bonded emulsifying agent. Polycyclodextrin beads may be used in chromatographic columns and as agents for removing polychlorinated biphenyl compounds from the environment.</p> |
