Abstract: The photoactive systems of thioxanthone derivatives were studied by N121 UV CURE TESTER at first. This is a new method for determining the photopolymerization rate of the photoactive systems by thioxanthone derivatives. The relationship between the wavelength of lamp and the wavelength absorption of photoinitiator was discussed.

Key words: thioxanthone, photoinitiator, photopolymerization
