Photoinduced Unzipping Depolymerization of Poly(olefin sulfone)s Possessing Photobase Generator and Base Amplifier
The photoinduced depolymerization of poly(olefin sulfone)s was investigated. Poly(olefin sulfone)s possessing base-amplifying groups were synthesized. A photobase-generating compound was mixed with poly(olefin sulfone)s and irradiated with 254 nm UV light. The decomposition ratio was significantly enhanced in poly (olefin sulfone)s that possessed base-amplifying groups. (C) 2008 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 47: 602-613, 2009
