Abstract: [4-(2-hydroxy-3-butoxy-1-propoxy)phenyl]phenyliodonium hexafluoroantimonate (BPI·SbF6) was prepared by the reaction of 2-propanol,1-butoxy-3-phenoxy with [hydroxy(tosyloxy)io-do]benzene in approximately 79% yield. The later product BPI·SbF6 was identified by infrared spectrum, UV spectrum, 1HNMR spectrum and element analysis. The characteristic curves of pho-topolymerization system CY179/BPI·SbF6 with different concentration of initiator BPI·SbF6 and the characteristic post-curves of photopolymerization system CY179/BPI·SbF6 with different UV curing time were studied.

Key words: cationic photoinitiator, iodonium salt, photosensitive, post-curing
