A new visible light sensitive photoinitiator system for the cationic polymerization of epoxides
摘要：
This communication reports the development of an efficient three-component visible light sensitive photoinitiator system for the cationic ring-opening photopolymerization of epoxide monomers and epoxide functional oligomers. The photoinitiator system consists of camphorquinone in combination with a benzyl alcohol to generate free radicals by the absorption of visible light. Subsequently, the radicals participate in the free radical chain induced decomposition of a diaryliodonium salt. The resulting strong Brnsted acid derived from this process catalyzes the cationic ring-opening polymerization of a variety of epoxide substrates. 2008 Wiley Periodicals, Inc.
