ABSTRACT:
The process 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 and emulsifying agent to form the spherical polymer bead.
