Abstract
A novel monomer, 1,1,1-tri-[4-(methacryloxyethylaminocarbonyloxy)-phenyl]ethane (MPE) can be used in preparing dental compositions The MPE monomer can be combined into a dental adhesive with hydroxyethyl methacrylate (HEMA) and BisGMA (bisphenol A dimethacrylate). The MPE polymer can be polymerized with a photoinitiator system, such as a system that includes an iodonium salt. The iodonium salt can be diphenyliodonium hexafluorophosphate.
