Synthesis and characterization of a novel resin monomer with low viscosity

In this study, we designed and synthesized a novel macromolecule (tetramethyl bisphenol F acrylate, TMBPF-Ac) with low viscosity, excellent mechanical properties and biocompatibility. It could be used as a monomer for dental resin composites, which could reduce the risk of human exposure to BPA derivatives in the oral environment. In addition, the monomer could be used without diluent, so as to avoid the negative effect of diluent. Methods TMBPF-Ac was synthesized by multistep condensation reaction. Its structure was confirmed by 1H NMR spectra. Different resin mixtures were prepared, and then a variety of performance and cytotoxicity tests were carried out on those specimens. Results 1H NMR spectra showed that the structure of TMBPF-Ac was in accordance with the design. The viscosity of TMBPF-Ac was obviously lower than that of Bis-GMA. Three kinds of resins were all in line with ISO 4049: 2009 and ISO 10993-5:2009. TMBPF-Ac based resin had better physical and biological properties. Graphical abstract
