Synthesis and photopolymerization characteristics of amine coinitiator

Four different amines were synthesized by Michael addition using different space length of acrylate with octylamine. The structure was identified by 1H 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.
