Synthesis, characterization, photo polymerization and hydrolytic stability of new diallyl self-etching monomer

In this study, considering the hydrolytic instability of most resin-based restorative adhesives in acidic and aqueous conditions, a dialyl self-etch monomer was synthesized and characterized by FT-IR and 1H-NMR spectroscopy. The new synthesized monomer contains a stable alylic group instead of instable ester group in conventional dental adhesive (meth)acrylate monomers. As it was expected hydrolytic stability was enhanced compared to the dimethacrylate monomer. The synthesized alylic monomer was also photo-cured under irradiation of visible light and and stored in water for more than 4 months. The dialyl self-etching monomer showed excellent hydrolytic stability along. The monomer also showed to be able to etch tooth enamel
