Curable dental compositions and articles comprising polymerizable ionic liquids
First Claim
1. A curable dental composition comprising an ethylenically unsaturated compound with acid functionality and a polymerizable ionic liquid, wherein the polymerizable ionic liquid comprises an anion, a cation, and at least one free-radically polymerizable group selected from (meth)acryl, vinyl, or vinyl ethers, and wherein the polymerizable ionic liquid has an air to nitrogen curing exotherm ratio of at least 0.90.

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.
