Synthesis and Structural Characterization of Novel Urethane-Dimethacrylate Monomer with Two Quaternary Ammonium Groups

Abstract

Composite restorative materials with dimethacrylathe matrices are commonly used as dental fillings. They have good usable properties; however, they lack antibacterial activity. They may also promote secondary caries. A solution to that problem could be the application of monomers with microbiologically active quaternary ammonium groups. This research aimed at the synthesis of a new urethane-dimethacrylate monomer with a 1,3-bis(2-isocyanatopropan-2-yl)benzene (TMXDI) core, as well as two arms with quaternary ammonium group with the decyl subsistent. The structure of the obtained monomer was confirmed via FTIR and 1H and 13C NMR spectroscopies.
