Abstract
A novel photoinitiator called 2-methyl-2-benzoylethanolpentadecafluorooctanote (1173-F) was synthesized and characterized. 1173-F is an efficient photoinitiator for free radical photopolymerization in the presence of oxygen and has ability of moving to the surface. The oxygen inhibition of the photopolymerization surface could be decreased because the large amount of photoinitiator at the top to be consumed by oxygen. UV absorption spectroscopy, X-ray photoelectron spectroscopy, gel permeation chromatography, and EDS-line mapping were used to prove the migratory of 1173-F in monomers. Real time FTIR analysis was taken to investigate the ability of 1173-F to overcome oxygen inhibition.
