Abstract
Polymerizable cyclodextrin derivatives (PCDs) for use in dental applications are disclosed. Each PCD molecule contains covalently attached polymerizable groups, and may also contain other covalently attached functional ligand groups, and molecularly encapsulated comonomers, polymerization inhibitors (stabilizers), polymerization initiators, and other desirable molecules. The covalently attached groups are ether or ester substituents, or their derivatives, in statistically predetermined proportions. The molecular members of PCD libraries may have quasi-random molecular configurations in the numbers and locations of their various substituents. Appropriate formulations containing PCD libraries can yield unique structural adhesives and resins for use in health-care procedures.
