    Abstract: Adhesive compositions and methods of preparing an adhesive composition are described. The method comprises providing a syrup composition comprising a free-radically polymerizable solvent monomer and a solute (meth)acrylic copolymer, and radiation curing the syrup composition in the absence of an ionic photoacid generator. The solute (meth)acrylic copolymer comprises epoxy-functional groups, acid-functional groups, or a combination thereof. In some embodiments, an epoxy resin having on average greater than one polymerizable epoxy group per molecule or an acid comprising at least two carboxylic acid groups is utilized. The epoxy-functional groups and acid-functional groups of the (meth)acrylic copolymer or the adhesive composition can readily crosslink in the absence of an ionic photoacid generator (PAG).

    Abstract: Presently described are curable dental compositions comprising a polymerizable ionic liquid. The polymerizable ionic liquid comprises one or more ethylenically unsaturated (e.g. free-radically polymerizable) groups. Various embodiments of curable dental compositions are described. In some embodiments, the polymerizable ionic liquid is a monofunctional polymerizable ionic liquid comprising an ethylenically unsaturated group. In other embodiments, the polymerizable ionic liquid is a multifunctional polymerizable ionic liquid comprising at least two ethylenically unsaturated groups. The curable dental compositions describe herein can be utilized as dental primers, dental adhesives, dental sealants, and dental composites. In many embodiments, the curable dental compositions further comprise an initiator such as a photoinitiator.
