[Abstract]:In this paper, we focus on the design, synthesis and study of the new resin matrix. Through the design and synthesis of two new high performance and low viscosity composite resin matrix, and the structure of the composite resin matrix, the paper begins with the improvement of the performance of the composite resin matrix used in dentistry, focusing on the design, synthesis and properties of the new resin matrix. The performance and toxicity were studied in detail. Tetramethyl bisphenol F compound was synthesized by the condensation of hydroxyl aldehyde and reacted with epichlorohydrin to obtain tetramethyl bisphenol F type epoxy resin. A new composite resin monomer, tetramethyl bisphenol F type acrylate, was synthesized by the reaction of the epoxy resin with acrylic acid. The relationship between the structure and properties of the resin was studied and its biological toxicity was evaluated. The optimum compound resin system. 2. 2 was mixed with Bis-GMA in different proportion. A novel polymer containing trifluoromethyl-m-trifluoromethyl phenyl acrylate was designed and synthesized. The relationship between its structure and properties was studied and its biological toxicity was evaluated. The optimum compound resin system. 3. 3 was mixed with Bis-GMA in different proportion. The effects of different concentrations of TEGDMA on the properties and toxicity of two new composite resins were analyzed. The new composite resin matrix is expected to be a substitute for Bis-GMA.
