Four different amines were synthesized by Michael addition using different space length of acrylate with octylamine. The structure was identified by H-1 NMR. The photopolymerization kinetics of 2,2-Bis [4-(2-hydroxy-3-methacryloxypropoxy)phenyl]-propane (Bis-GMA)/triethylene glycol dimethacrylate (TEGDMA)/camphorquinone (CQ)/amine system was monitored by Real Time Fourier Transform Infrared (RTIR). The primary photoreaction of CQ/amine was investigated by UV spectra and fluorescence quenching. The results indicated that the chain length only had slight effect on the photopolymerization process.
