In this paper, the kinetic equation of photo-initiated reaction was set up by measuring the photoinitiator absorbency and the exposure time during the exposure process based on the spectroscopic analysis and reaction kinetics. And an effective and convenient computation model for quantum yields of photoinitiators was established through further analysis of the exposure process. The kinetics curve of photoinitiator 1173 (HMPP) was determined according to this method. The results show that the reaction is consistent with the kinetic model established in this paper. And the quantum yield is 2.4% at the main absorption peak (247nm).
