TI  - Investigation of 3,4-methylenedioxybenzene methoxyl methacrylate as coinitiator 
      and comonomer for dental application.
PG  - 487-93
AB  - 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 degrees C). MDBMM as a comonomer resulted in slightly higher 
      final double bond conversion than that of TEGDMA, which brought higher modulus 
      around 37 degrees C. Therefore, MDBMM can be used as both potential coinitiator 
      and comonomer for dental application.
