Abstract: Two water soluble benzophenone sensitizexs are examined through measurements of UV,phosphorescence spectra, quantum yields,liftime of phosphorescence and transient absorptionof flash photolysis. It has been found that the OH group in the side chain of sensitizerhas a great influence on the photoinitiation activity. A possible interpretation is suggested.

Key words: Benzophenone sensitizer, photopolymerization, Mechanism
