ABSTRACT:
A large class of crosslinked cyclodextrin resins soluble in water to an extent under about 200 ppm but soluble in an organic solvent to an extent of at least 0.1 weight percent have good film-forming properties with a wide variety of solid phase substrates. The films exhibit excellent adhesive properties toward virtually all solid surfaces which consequently can be readily coated with a thin film having a multiplicity of cyclodextrin moieties available at the surface for seperation and/or purification. Such coated substrates can be prepared in a variety of sizes, shapes, and cyclodextrin loading quite conveniently and relatively inexpensively.
