With the improvement of environmental protection consciousness, the photopolymerization technology has greatly developed over the past ten years due to its high efficiency and environmental protection, and become one of the most advanced technologies. In the present paper, the kinds and related initiating mechanisms of photoinitiators as the key component in photopolymerization system were discussed, and furthermore the progress of photoinitiators for free radical photopolymerization in the recent years was reviewed.

Key words: Photoinitiator, Photopolymerization, LED
