Abstract
Polymerizable cyclodextrin derivatives (PCDs) are disclosed, wherein each molecule contains at least one covalently attached polymerizable group, may also contain one or more other covalently attached functional ligand group(s), such as free carboxyl group(s), may also contain molecularly encapsulated comonomers, polymerization inhibitors (stabilizers), and polymerization initiators. The groups are attached covalently as ether or ester derivatives in statistically predetermined proportions, in a homogeneous solution, to form a 'combinatorial' library having quasi-random molecular configurations of free carboxyl or other ligand groups. In the resulting PCD library, appropriate comonomers and polymerization initiators can be added that will enable timely polymerization to form unique structural adhesives and resins. The adhesive resins can be utilized in preventative and restorative dentistry.
