Abstract
Disclosed are compositions that comprise vinylarylalkylene ethers of cyclodextrins optionally containing ether-linked adhesion-promoting groups, in combination with copolymerizable monomer or monomers. The copolymerizable monomer or monomers may include vinylarylalkylene ethers of oligohydroxy compounds (for example, sorbitol divinylbenzyl ether and others). The composition further may include stabilizers (for example, 1,3,5-trimethyl-2,4,6-tris(3,5-di-(tert)-butyl-4-hydroxybenzyl)benzene and others), and polymerization initiators (for example, phenylbis[2,4,6-trimethylbenzoyl]phosphine oxide and others) and reinforcing materials (for example, imogolite). Methods of preparing the compositions as well as the components of compositions and methods for their use in dental and other applications are also disclosed.
