- Abstract
Isobornyl acrylate (IBOA) and isobornyl methacrylate (IBOMA) were used to replace triethylene glycol dimethacrylate (TEGDMA) as reactive diluents in dental restorative materials. Photopolymerization behaviors of mixtures of IBO(M)A and 2,2-bis[ p-(2′-hydroxy-3′-methacryloxy propoxy)phenyl]propane (Bis-GMA) were investigated by Fourier transform infrared spectroscopy. The degree of conversion, volume shrinkage, contact angle, water sorption, water solubility, flexural strength, and modulus values of the Bis-GMA/IBO(M)A formulations were measured and compared with those of a Bis-GMA/TEGDMA formulation. The results illustrate that the degree of conversion, volume shrinkage, contact angle, water sorption, flexural strength, and modulus values of the Bis-GMA/IBO(M)A systems were all lower than those of the Bis-GMA/TEGDMA system; the water solubility values of the Bis-GMA/IBO(M)A systems were higher than that of the Bis-GMA/TEGDMA system. © 2012 Wiley Periodicals, Inc.
