摘要
Abstract In this study, 3,4‐methylenedioxybenzene methoxyl methacrylate (MDBMM) was synthesized for the purpose of replacing both triethylene glycol dimethacrylate (TEGDMA) and tertiary amine, which was usually used as a comonomer and coinitiator for dental resin, respectively. Urethane dimethacrylate (UDMA) was chosen as a monomer. Real time near Fourier transform infrared (FTIR) with a horizontal sample holder and dynamic mechanical analyzer (DMA) were used to study the kinetics and mechanical properties, respectively. The results showed that the addition of MDBMM as a coinitiator in UDMA/TEGDMA/CQ (70/30/0.5 wt %) system led to the increase of the rate of polymerization. When compared with the commercial polymerizable amine, 2‐( N , N ‐dimethyl amino)ethyl methacrylate (DMEM), MDBMM showed comparable initiating reactivity and led to higher modulus around human body temperature (37°C). MDBMM as a comonomer resulted in slightly higher final double bond conversion than that of TEGDMA, which brought higher modulus around 37°C. Therefore, MDBMM can be used as both potential coinitiator and comonomer for dental application. © 2007 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2007
