摘要

In this work the room-temperature photopolymerization of Bis-GMA, Bis-EMA, urethane dimethacrylate (UDMA) and triethylene glycol dimethacrylate (TEGDMA) induced by camphoroquinone/N,N-dimethylaminoethyl methacrylate, as photo-initiator system, was followed by FT-IR. The results obtained were then fitted by a non-linear least square method to a rational function, which permitted the accurate calculation of the limiting degree of conversion. The latter was found to increase in the order Bis-GMA < Bis-EMA < UDMA < TEGDMA. This trend is discussed in connection with the chemical structure of dimethacrylates. The photopolymerization of mixtures of Bis-GMA/TEGDMA, Bis-GMA/UDMA and Bis-GMA/Bis-EMA showed a good linear relationship of degree of conversion with the mole fraction of Bis-GMA and in the case of the first pair also with the Tg of the initial monomer mixture.
