Abstract
The polymerizable cyclodextrin derivatives ('PCDs') of this invention relate to cyclodextrin derivatives wherein substantially each molecule of which contains one or more covalently attached polymerizable group or groups, may also contain one or more other types of functional groups covalently attached, may also have other types of molecules that are complexed or more particularly within the otherwise empty spaces within the cyclodextrin derivatives, and combinations and permutations of these characteristics. The PCDs are referred to herein as 'MCDs' when only methacrylate groups comprise the polymerizable groups of the PCDs. These PCDs are organofunctional monomers that are derivatives of one or more forms of cyclodextrin, hydroxyalkyl cyclodextrins, or both ('CDS'), the molecules of which to a very high probability contain no fewer than one polymerizable group per molecule and also to a very high probability contain no fewer than one ligand group per molecule and optionally may contain molecularly encapsulated molecules within the PCDs.
